So anatase titanium oxide can separate electrum and cavity more effectively. At the same time, anatase has better photoactivity than rutile. Therefore it is significant to research how to prepare stable anatase titanium oxide film. On the other hand, titanium oxide absorbs ultraviolet light strongly (absorption edge is at 380nm) but visible light weakly.

在光催化方面TiO_2的激发必须在高能量的紫外光下才能进行，而到达地面的太阳能中只有3-4%的紫外光，人工紫外光又价格昂贵，所以将光激发红移到可见光区，可降低成本、节省能源。

In this study, AlGaN/GaN hetero-junction photo-transistors in detecting ultraviolet spectra have been fabricated and characterized. One of the HPTs features as low-temperature grown GaN insertion layer between based and emitter layers to reduce dark current. The internal gain and response time are also studied for the HPTs with and without the LT-GaN layer.
