Abstract We propose ANN-based models to analyze and extract the internal parameters of a Schottky photodiode (SPD) without presenting them with any knowledge of the highly nonlinear thermionic emission (TE) expression of the device current. We train,

In this article, evidence for the existence of illumination and bias-dependent negative differential conductance (NDC) in Ni-doped Al/ZnO/p-Si Schottky diodes, and the possible mechanism for its origin, are presented. The atomic percentages of Ni dop

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

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
