Abstract
1-(2-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-2-oxoethyl)pyridinium chloride (DOPC) was chemically synthesized and showed thermal stability up to 220 °C. DOPC powder has polycrystalline structure and crystallizes in triclinic structure with space group, \( P\bar{1} \). Miller indices for each diffraction plan in X-ray diffraction spectra are determined. DOPC films have been prepared via spin-coating technique onto quartz and silicon single crystal substrates. The optical properties of the films are investigated by spectrophotometric measurements of the transmittance and reflectance over the spectral range 200–2500 nm. The absorption coefficient and the refractive index of the films are calculated in which the optical band gap and single oscillator parameters are estimated. Hybrid Au/DOPC/p-Si/Al heterojunction is constructed, and the dark current–voltage characteristics are recorded. The device exhibited rectification behavior and the basic parameters such as ideality factor, barrier height, series resistance and charge carrier mobility are evaluated.
