Persistent photoconductivity effect
Web15. nov 2024 · The persistent photoconductivity (PPC) effect in the InAs nanowires has not been previously studied in detail despite its importance for the material photoresponse. … WebCharging effects in an AlxGa1 xN/GaN heterostructure field-effect transistor epitaxial layer structure have been studied using scanning capacitance microscopy. Voltages of 6 V applied between an AlxGa1 xN/GaN sample structure and a conducting proximal probe tip are found to create trapped charge in both doped and undoped heterostructures.

Web1. júl 1997 · Both the conductivity and thermopower are changed by light exposure, but no change is observed in the difference between the conductivity and thermopower activation energies for any of the samples studied here. This suggests that the long-range disorder is unaffected by light exposure.

Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation. When light is absorbed by a material such as a semiconductor, the number of free electrons and holes increases, resulting in increased electrical conductivity. To cause excitation, the light that … sed sc consultasWebThe results of an analytical study of the photoconductivity decay (PCD) method for measuring carrier lifetimes of n‐type HgCdTe show that the measurements give much higher values than the minority carrier lifetimes when trapping is significant. In contrast, for p‐type HgCdTe, the PCD method gives results equal to or less than the minority carrier lifetime … sed sc cbtcWebAbstract: Bone injury and implantation operation are often accompanied by microenvironment damage of bone tissue, which seriously affects the process of osseointegration of implants, especially for titanium (Ti)-based bioinert materials.
