I-V Characterization of TEA-Capped CdSe Thin Films on Al and FTO Substrates

What is it about?

The study focuses on the construction and characterization of capped CdSe Schottky diodes. TEA-capped CdSe nanoparticles were deposited on aluminum (Al) and fluorine tin oxide (FTO) substrates using drop-casting. The ideality factor was 8 for Al and 11 for FTO. SEM images showed spherical CdSe nanoparticles with an average particle diameter of 55 nm. XRD patterns confirmed the cubic structure of CdSe and the nanoscale particle size. I-V curves for both diodes demonstrated nonlinear and rectifying characteristics, with rapid forward current growth and modest reverse current. The study examines the effect of substrate on the electrical characteristics of metal-semiconductor contacts of CdSe-TEA thin films.
