A natural dye-based Schottky diode with observed quantum tunnelling and determined trap density, mobility, and excellent sensitivity and nonlinearity

Trap density (N_t), density of carriers (n_o) and mobility are extracted in Al/beetroot/Cu Schottky diode using the Poisson’s equation. The trap density and carrier concentration were found to be 1.25 × 10⁹ and 1.8...
