Self-heating (SH)-induced electrical and optical switching in high quality VO2 films grown by magnetron sputtering on a c-cut sapphire substrate has been investigated under various applied constant current pulses (ID). The effect of SH on the behavio

This study focuses on the effect of the substrate temperature (TS) on the quality of VO2 thin films prepared by DC magnetron sputtering. TS was varied from 350 to 600 °C and the effects on the surface morphology, microstructure, optical and electric

Electrical and optical properties Cs-doped a-Se0.95As0.05 (stabilized a-Se that has been alloyed with As) have been investigated. As expected there was no electron paramagnetic resonance signal on Cs-doped films or bulk samples, which put the spin-ac
