Abstract The laser-induced effects on dielectric properties of chalcogenide glass (ChGs) have been present in a glassy system of Se–Te–Sn–Cd for possible applications in optics and optoelectronics such as light-controlled capacitance-based touch displays. The temperature/frequency dependence of dielectric relaxation before and after laser exposure was investigated by using laser sources of different wavelengths (405 nm, 532 nm, 690 nm, and 785 nm). The result showed the presence of laser-induced residual effects on dielectric properties (dielectric constant/loss and a.c. conductivity) after the exposure of continuous-wave laser sources of chosen wavelengths. Further analysis indicates that the modification in the meta-stable state due to self-organization is the feasible mechanism of observed persistent light-sensing effects.

Se-Te-Sn-Cd 玻璃态半导体的激光诱导自组织用于开发新型光敏电介质

摘要 激光诱导对硫属化物玻璃 (ChGs) 介电性能的影响已经存在于 Se-Te-Sn-Cd 的玻璃态系统中，可用于光学和光电子学，例如基于光控电容的触摸显示器。通过使用不同波长 (405 nm、532 nm、690 nm 和 785 nm) 的激光源研究了激光曝光前后介电弛豫的温度/频率依赖性。结果表明，在暴露选定波长的连续波激光源后，存在激光诱导的对介电特性（介电常数/损耗和交流电导率）的残余效应。进一步的分析表明，自组织引起的亚稳态的改变是观察到持续光敏效应的可行机制。
