NiO Quantum dots Doped Triple Cation Perovskite \(\mathrm{CsMAFAPbI_2Br_2}\) Heterojunction Photodetector with High Responsivity

Advances in Science, Technology and Engineering Systems Journal, Volume 7, Issue 3, Page # 161–165, 2022; DOI: 10.25046/aj070318
Abstract:

Optoelectronic devices applications based on Organic–inorganic perovskites are promising and effective low-cost energy materials due to their exceptional physical properties which include high carrier mobility, high optical absorption coefficient, and long carrier diffusion length. In the presented work, a TiO2/NiO+5% Fe quantum dots (QDs)–doped CsMAFAPbI2Br2 perovskite heterojunction broadband photodetector was fabricated on FTO/glass substrate. The…

Synthesis and Characterization of CN Thin Films Produced by DC-Pulsed Sputtering in an \(CH_3CH_2OH-N_2\) Atmosphere

Advances in Science, Technology and Engineering Systems Journal, Volume 7, Issue 1, Page # 53–59, 2022; DOI: 10.25046/aj070106
Abstract:

This paper reports on the successful deposition of amorphous carbon nitride thin films (a-CNx). Samples were deposited using a DC-pulsed sputtering technique in CH3CH2OH-N2 atmosphere at constant pressure (1 Torr). Raman spectra were collected to investigate the bonding structure of the deposed thin films, while scanning electron microscopy (SEM) and atomic force microscopy (AFM) were…
