Synthesis of CuAlS2 as p-type transparent conductors: towards fully transparent electronics
Available from Jan. 2023
Project motivation: Transparent conductive materials (TCMs) are an essential component for electronic devices such as LEDs, transistors, p-n junctions and solar cells. However, the p-type TCMs lack in performance compared to n-type counterparts. This challenge is a hindrance in achieving a fully transparent electronic device. Numerous promising p-type TCMs have been predicted computationally, and realization of such TCMs have been a daunting task. In this project we will work on one of ternary chalcopyrite CuAlS2. (Ref. R. Woods-Robinson et al. Chem. Rev. 2020, 120, 4007−4055).
Project goal: To demonstrate the transition from metallic CuAl films to semiconductor CuAlS2 films. The CuAl films are made via sputtering and will be subjected to sulphurisation to form CuAlS2.
Tasks of MSc student: The CuAl films will be deposited by DC sputtering, followed by a thermal sulphurisation step. The structure of CuAlS2 will be confirmed using x-ray diffraction (XRD). Optical and electrical characterization of the films’ properties will be determined using UV Vis NIR spectrometer and van der pauw method using hall effect respectively. The optoelectronic properties will be optimized by varying the parameters during sulphurisation.
