Asymmetric Electrode-Driven Self-Powered Photodetector Using Cu2-xS Film

ACS Applied Electronic Materials, 2025
Self-powered photodetectors through asymmetric contact modulation are a simple and efficient approach that has gained a lot of attention because they form an energy gradient in the band gap of the semiconductor. This energy gradient develops the self-assembly of the built-in electric field to separate the electron–hole pairs without any external bias, which facilitates long-term functioning of the device. Copper sulfide (Cu2-xS) is a promising p-type semiconductor for visible-near-infrared photodetectors due to its tunable band gap and electrical properties. In this work, a Cu2-xS-based metal–semiconductor–metal (MSM) photodetector with asymmetric electrodes (Au/Cu2-xS/Ag) is fabricated, and its photodetector properties are measured under visible and near-infrared (NIR) light illuminations. The fabricated Au/Cu2-xS/Ag structured device shows responsivity of 5.66 × 10–3 A/W and 11.24 × 10–3 A/W under visible (λ = 530 nm) and NIR (λ = 980 nm) light illuminations, respectively, even at zero bias. Finally, the obtained results attest that the fabricated self-powered photodetector is highly suitable for modern self-powered optoelectronic applications.

Self-Powered Photodetector Based on p(Cu2O)–n(MoO3) Junction Architecture: Analyzing the Influence of Depletion Region Width on the Photodetector Properties
Anibrata Mondal, Karthickraja Ramakrishnan, Sourav Deb, B. Ajitha, Y. Ashok Kumar Reddy
ACS Applied Energy Materials, 2025
In this study, the fabrication of the p–n junction photodetector (PD) based on p-type Cu2O and n-type MoO3 semiconductor, which shows a broadband photoresponse (ultraviolet to near-infrared) at self-powered mode, is presented. The thin films are grown through the sputtering technique by varying the depletion region width (DRW) by 2 mm, 3.5 mm, and 5 mm, and the photodetector properties are studied. The fabricated device with a DRW of 3.5 mm, depending on the generation of a stronger electric field, with less recombination of the charge carriers at the depletion region, results in achieving higher photodetector properties. Consequently, the Ag/Cu2O:MoO3/Ag@DRW of the 3.5 mm device shows the highest photocurrent of 16.6 and 39.12 nA under the illumination of 550 and 1000 nm wavelengths. Furthermore, the photodetector properties of the device fabricated on the polyethylene terephthalate (PET) substrate are studied by applying a bias voltage. At 5 V bias voltage and under the illumination of UV light, the Ag/Cu2O:MoO3/Ag@DRW of a 3.5 mm device grown on the PET substrate shows the Rλ of 11.4 μA/W and D* of 1.45 × 106 Jones. Finally, these superior figures of merit of the fabricated device signify the development of the self-powered photodetector with broadband photodetection.
Growth Control of Cu2-xS Films for Visible-Near Infrared Photodetectors
Karthickraja Ramakrishnan, Y. Ashok Kumar Reddy, B. Ajitha
ACS Applied Electronic Materials, 2025
Nanostructured plasmonic copper sulfide (Cu2-xS), from the family of transition-metal sulfides with tunable optical and electrical properties, has drawn significant attention for broadband photodetectors in our research society. Herein, the attempt is made to grow Cu2-xS films via sulfurization of copper (Cu) films through the chemical vapor deposition (CVD) technique at different sulfurization temperatures (200–400 °C). A hexagonal structured CuS phase is observed for the film grown at 300 °C, with a higher crystalline nature confirmed through structural analysis. Surface compositional analysis suggests that the film deposited at 300 °C exhibits more copper vacancies, which shows the greater diffusion of sulfur atoms into copper films, which leads to the formation of well-aggregated nanospheres with larger grains over the film’s surface. Moreover, the band gap of the grown films is observed in the range of 1.79–1.92 eV, and the localized surface plasmon resonance (LSPR) band is observed in the near-infrared (NIR) region through optical studies, which confirms the plasmonic nature of Cu2-xS. Furthermore, the photodetector properties of the Au/Cu2-xS/Au test device are investigated in terms of photoresponsivity (Rλ), specific detectivity (D*), and external quantum efficiency (EQE) under visible and NIR light illuminations. The film grown at 300 °C exhibits superior results such as Rλ of 2.48 ± 0.02 A/W and 5.10 ± 0.02 A/W, D* of 3.02 ± 0.02 × 1012 Jones and 6.21 ± 0.02 × 1012 Jones, and EQE of 581 ± 5% and 646 ± 5% under visible (λ = 530 nm) and NIR (λ = 980 nm) light illuminations, respectively, with lower incident power density at a bias voltage of 3 V, which signify the potential of the fabricated test device in the broadband photodetectors.

Effect of Substrate Temperature on Cu-xO Growth for Enhanced Photodetector Performance in Visible Region
Karthickraja Ramakrishnan, Y. Ashok Kumar Reddy, B. Ajitha
IEEE Sensors Journal, 2024
The present study investigates the effect of substrate temperature (30 °C–300 °C) on the sputter-deposited Cu2-xO films for improved photodetector performance in the visible region. Cubic structured Cu2O phase is observed for all deposited films through structural analysis. Increasing substrate temperature causes the formation of nanospheres with higher grain size at 200 °C confirmed by the morphological images. Moreover, all the deposited thin films show a strong absorption band in the visible region (526–550 nm). Among deposited films, a lower bandgap (2.02 eV) is observed for the film deposited at 200 °C due to the higher surface area-to-volume ratio and increased grain size. The better crystalline nature, more copper vacancy, and formation of nanospheres with a larger grain size of the film deposited at 200 °C result in higher mobility and conductivity. Furthermore, the photodetector performance of the Au/Cu2-xO/Au test devices is studied under the visible light ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula> = 530 nm) irradiation. Among samples, the sample grown at 200 °C showed higher photocurrent ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$36.10~\mu \text{A}$ </tex-math></inline-formula> ), <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${I}_{\text {on}}/{I}_{\text {off}}$ </tex-math></inline-formula> ratio (183.50), photoresponsivity (1.127 A/W), specific detectivity ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${22.40} \times {10}^{{11}}$ </tex-math></inline-formula> Jones), and faster response times ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\tau _{r}$ </tex-math></inline-formula> = 92 ms and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\tau _{f}$ </tex-math></inline-formula> = 84 ms) even at lower incident optical power density (0.1283 mW/cm2). These improved experimental results signify the potential of the fabricated test device at 200 °C for the optoelectronics devices.
