In this article, a new Schottky diode based on a transparent conducting polymer 2-(4-fluorophenyl)-2-oxoethyl-2-methylprop-2-enoate (PFPAMA) that is doped up to 5% with ZnO is presented. PFPAMA is a promising transparent polymer that is inclined towa

Calcium phosphate ceramics with various Ca/P ratios of 1, 2, 3, 4 and 8 were synthesized via sol-gel route. The effects of Ca/P molar ratio on structural, morphological, dielectric and antimicrobial properties were investigated in detail using X-ray

We present evidence for the existence of bias and illumination-driven negative differential conductance (NDC) in Ni-doped aluminium/p-Silicon Schottky diodes. We suggest the Ridley–Watkins–Hilsum (RWH) mechanism as a possible explanation of the o

In this study, we examine the performance of organic field-effect transistors (OTFTs), based on pentacene as an active layer. We investigate two different thicknesses of pentacene film (280 nm and 150 nm) deposited on a poly(4-vinylphenol) layer grow
