论文摘要
由于其带隙低和光学效率高，因此被认为是中红外应用的重要材料。利用其结构各向异性，我们制造了柜员纳米线设备，并研究了在中红外照明下通过极化分辨的光导频光谱的辐射相互作用。光峰值的强度表现出对温度的敏感依赖性，并且可以通过后门的正电压偏置显着提高。
Due to its low bandgap and high optical efficiency, tellurium is considered an important material candidate for mid-infrared applications. Taking advantage of its structural anisotropy, we fabricated tellurium nanowire devices and investigated the radiative interaction of charge carriers by the polarization-resolved photoconductivity spectra under mid-infrared illumination. The intensity of the photoresponse shows sensitive dependence on temperature and could be significantly boosted by positive voltage bias from the back gate.
