Optical Characterization of Intrinsic Silicon Thin Films Growth via Hot Wire in Plasma-Very High-Frequency PECVD A W Nuayi, R Ruslan, F A Noor, T Winata, Irzaman Journal of Physics Conference Series, 2025 This study investigated the growth of a thin intrinsic silicon layer on a 1.5 x 2 cm glass substrate. The growth utilized a Hot Wire in Plasma-Very High-Frequency Plasma Enhanced Chemical Vapor Deposition (HW IP-VHF PECVD) system at varied substrate temperatures (200, 225, 250, and 275 °C). The VHF PECVD method served as a comparative benchmark. Silane gas (SiH4) was introduced at 70 sccm to enhance growth. This research seeks to preliminarily optimize the optical properties of type-i polycrystalline silicon thin films for future application in p-i-n silicon-based graphene solar cells. Optical characterization was conducted using a UV-Vis and NIR spectrometer across the 300 – 1100 nm spectrum. The findings illustrate the intrinsic silicon film’s optical response at wavelengths exceeding 600 nm. Comparative analysis indicates lower transmittance for films grown via HW IP-VHF PECVD than VHF PECVD. Notably, at 275 °C substrate temperature, the intrinsic silicon film exhibited a 54.65% increase in average absorption compared to VHF PECVD. Furthermore, average absorbance increases of 1.61, 10.51, and 14.24 were recorded at 200, 225, and 250 °C substrate temperatures, respectively. The HW IP-VHF PECVD method yielded reduced Egap values of 7.81, 12.90, 2.82, and 4.82% at 200, 225, 250, and 275 °C substrate temperatures. This study underscores the potential for optimizing optical properties through controlled growth conditions using HW IP-VHF PECVD.
The Influence of Annealing Temperature on the Grain Size of a Nickel Metal Catalyst Suitable for Carbon Nanotube Growth Rustan Ruslan, Abd. Wahidin Nuayi, Ajeng Eliyana, Fatimah Arofiati Noor, Toto Winata Journal of Physics Conference Series, 2025 The catalyst plays a key role in the growth of carbon nanotubes (CNTs) functioning as a guiding medium in the growth process. In this research, a nickel (Ni) catalyst was on a 7101 glass substrate using the thermal evaporation method. First, the effect of the thickness of the layer on its morphology was investigated, with thicknesses of 30, 40, 50, and 60 nm examined. An optimum density was obtained at 50 nm, at which the Ni particles attained the highest average diameter of 4.23 nm, and polydispersity index lower than the other samples, at 5.87%. Energy-dispersive X-ray spectroscopy results also showed a positive linear relationship between the thickness of the layer and both its mass and purity. Samples at this optimum thickness were annealed at 300 °C, 400 °C, or 500 °C for 4 hours to refine the crystal structure of the catalyst and produce small, uniform features. The samples annealed at 500 °C had the greatest average particle diameter of 5.92 nm and the lowest polydispersity of 5.76%. With a Ni catalyst that has a low polydispersity and thus a high level of uniformity, CNTs with a good level of uniformity and quality can also be obtained.
Enhancing Growth of Multi-Layer Graphene Synthesis on Glass Substrate though Ni Catalyst Annealing Using Hot Wire in Plasma Very High-Frequency PECVD Method A W Nuayi, F A Noor, E Sustini, Irzaman, T Winata Journal of Physics Conference Series, 2024 This study synthesized multi-layer graphene on a glass substrate using the high-frequency plasma-enhanced vapor deposition method with a hot wire in plasma. In the growth process, plasma was generated from methane gas (CH4) using an RF power generator at 70 MHz frequency and nickel (Ni) as the catalyst, which is deposited and annealed beforehand. This study aims as a preliminary to obtain optimum parameters for MLG growth using the HW IP-VHF-PECVD method. Raman spectroscopy, utilizing a 532 nm laser and an 1800 g/mm grating, detected distinctive D-band, G-band, and 2D-band peaks at wave numbers of 1335.31, 1607.74, and 2660.99 cm−1, respectively, in unannealed catalyst samples. Raman analysis, incorporating the I2D/IG ratio, revealed the presence of multi-layer graphene exhibiting diverse ratios (0.07 – 0.22) and crystal sizes (15.62 – 20.70 nm). SEM analysis demonstrated enhanced homogeneity in grain size and uniformity in thickness following Ni catalyst annealing. EDS confirmed the successful growth of graphene with carbon identified as the primary element. The annealing process at 400 °C for two hours resulted in graphene with a higher mass percentage and a more significant percentage of carbon atoms. These findings underscore the potential of the HW IP-VHF-PECVD method for producing multi-layer graphene, particularly in the context of solar cell applications, with further optimization of parameters.
Enhancement of photon absorption on Ba x Sr 1 - X TiO 3 thin-film semiconductor using photonic crystal Abd. Wahidin Nuayi, Husin Alatas, Irzaman S. Husein, Mamat Rahmat International Journal of Optics, 2014 Enhancement of photon absorption on barium strontium titanate (BaxSr1-xTiO3) thin-film semiconductor for mole fractionx=0.25, 0.35, 0.45, and 0.55 using one-dimensional photonic crystal with defect was investigated experimentally. The thin film was grown on transparent conductive oxide (TCO) substrate using chemical solution deposition method and annealed at 500°C for 15 hours with increasing rate of 1.6°C/min. From optical characterization in visible spectrum it was found that the average absorption percentages are 92.04%, 83.55%, 91.16%, and 80.12%, respectively. The BST thin film with embedded photonic crystal exhibited a relatively significant enhancement on photon absorption, with increasing value of 3.96%, 7.07%, 3.04%, and 13.33% for the respective mole fraction and demonstrating absorbance characteristic with flat feature. In addition, we also discuss the thin-film properties of attenuation constant and electrical conductivity.
The effect of Ba/Sr ratio on electrical and optical properties of Ba x Sr (1-x)TiO3 (x = 0.25; 0.35; 0.45; 0.55) thin film semiconductor Irzaman, Heriyanto Syafutra, Endang Rancasa, Abdul Wahidin Nuayi, Tb Gamma Nur Rahman, et al. Ferroelectrics, 2013 Ferroelectric BaxSr(1-x)TiO3 thin film semiconductors with Ba/Sr ratio deposited on silicon using chemical solution deposition (CSD) method have been investigated, followed by annealing at 850°C for 15 hours. Observations by I-V meter, LCR meter, and oscilloscope were employed to characterize the electrical properties of the thin films and the observation of fourier transform spectroscopy (FTIR) and particle size analyzer (PSA) to characterize the optical properties. The results showed that the dielectric constant was given around 2–18. Moreover the obtained films were found to be resistor because the I-V graph of each sample was ohmic either in dark or bright environment. The increase of BST mol fraction at dark environment is proportional to the increase of the curve slope. While at bright environment gives the highest curve slope for BST with fraction x = 0.45. Based on electrical conductivity of thin films, we conclude that the thin films are semiconductor. Moreover, functional group and particle size of sample were analyzed using FTIR and PSA analyzer. The augmentation of Ba would decrease the transmittance band of OH− and increase the transmittance band of C-O because the radius of Ba is higher than Sr. The particle distribution size of BST 0.45 is 134.93 nm smaller than BST 0.25 which gives 186.26 nm, BST 0.35 gives value of 467.86 nm and BST 0.55 is 407.49 nm.
