Study Influence of a Magnetic Field on Thin Film of (CdTe) Preparation via PLAL

This work used pulsed laser ablation to influence a magnetic field to create CdTe (NPs) by using distilled water. According to X-ray diffraction results, the CdTe (NPs) product in a magnetic field is more crystalline. UV-Vis tests showed that CdTe (NPs) had an optical band gap shift from (1.75) eV to (2) eVEnergy-dispersive X-ray mapping confirmed the synthesis of CdTe (NPs) with a weight percentage ratio of 96% [Cd]/[Te]; the photoluminescence (PL) spectrum confirmed the emission of a solid and broad peak at (651.139). The current characteristics of the n-CdTe/p-SiHJ exhibit rectifying behavior when a magnetic field is applied., with the rectification factor rising from (48.351) to (62.105). The manufactured photodetector's spectral operating region was visible, with improved responsivity at 660 nm, increasing from 0.72 A/W to 0.84 A/W.
