嵌有纳米晶的TiO $_2$玻璃中异质晶格电子跃迁的窄带光电探测
Narrow-band photodetection by heterolattice electronic transitions in TiO$_2$ glass embedded with nanocrystals
摘要：
在这封信中，我们提出，窄带光电探测可以实现在皮肤层的半导体与空间分离的光激发载流子从纳米异质晶格电子跃迁（NanoHLETs）。NanoHLET光电探测证明通过测量嵌入金红石和金红石TiO $_{2}$纳米晶体的TiO $_{2}$玻璃的$\sim$ 1 $μ$ m厚膜的光电导响应。由于$_{2}$玻璃薄膜中只含有金红石纳米晶，其响应曲线只有一个中心位于423.0 nm的尖峰，半高宽（FWHM）为13.7 nm。这种NanoHLET机制可能为制造与当前纳米级电子技术相匹配的超小型窄带光电探测器开辟一条新途径。
英文摘要：
In this letter, we propose that the narrowband photodetection can be realized in the skin layer of semiconductors with the spatially separated photo-excited carriers from the nanoscale heterolattice electronic transitions (NanoHLETs). The NanoHLET photodetection is demonstrated by measuring the photoconductive responses of the $\sim$ 1 $μ$m thick films of TiO$_{2}$ glass embedded with rutile and anatase TiO$_{2}$ nanocrystals. As containing only rutile nanocrystals, the TiO$_{2}$ glass film presents the responsivity curve with only one sharp peak centered at 423.0 nm with a full-width-at-half-maximum (FWHM) of 13.7 nm. This NanoHLET mechanism may open a new way in making ultra-small narrow-band photodetectors matching the current nanoscale electronic technology.
