Selective light-induced mass transport in amorphous $As_{x}Se_{100-x}$ films driven by the composition tuning: effect of temperature on maximum acceleration
摘要：
在用带隙光照射非晶$As_{x}Se_{100-x}$膜的情况下，观察到膜材料的横向质量输运改变了区域（4 < x < 5原子%）中的运动方向。拓扑结构转换（从“明到暗”到“从暗到明”的交叉）。我们提出了一个模型，定性地描述所观察到的现象。在开尔文探针力显微镜的模型的实验测试中，第一次据我们所知，它被检测到，随着温度的增加（从环境温度到玻璃化转变温度，Tg）光诱导的质量传输在玻璃半导体发生的速率，这显着超过那些在室温下。
英文摘要：
Under irradiation of amorphous $As_{x}Se_{100-x}$ films by band-gap light, it was observed that lateral mass transport of the film material changed the direction of movement in the region (4 < x < 5 at%.) of topological structural transition (crossover "from light to dark" to "from dark to light"). We propose a model that qualitatively describes the observed phenomenon. In experimental testing of the model by Kelvin probe force microscopy, for the first time to our knowledge, it was detected that with the increase of temperature (from ambient to glass-transition temperature, Tg) photo-induced mass transport in glassy semiconductors occurs with the rates, which significantly exceed those at room temperature.
