摘要
本文报道了高剂量电子辐照制备二碲化钼样品的研究。采用2 MeV Van de Graaff加速器，在1.3 MeV电压、5 μA电流、25 kGy/min剂量率、1000 kGy总剂量下辐照样品。当辐照剂量改变为50、100、200和500毫摩尔时，这些条件保持不变。通过高分辨率透射电子显微镜对样品进行分析，获得了用于生产MoTe2纳米管的最佳用量。MoTe2纳米管的最有效生产在100和200 Mrad之间。在MoTe2衍射图中观察到的角度为4、5、7、8和12°的旋转结构具有非常典型的特征。
OPTIMIZATION OF THE ELECTRON IRRADIATION IN THE PRODUCTION OF MoTe2 NANOTUBES
In this paper, we report the study of the production of MoTe2 (molybdenum ditelluride) samples after a high dose of electron irradition. A 2 MeV Van de Graaff accelerator was used to irradiate the sample at the following conditions: 1.3 MeV voltage, 5 μA current, 25 kGy/min dose rate, and 1000 kGy total dosage. These conditions are maintain fixed while the irradiation dosages were changed to 50, 100, 200, and 500 Mrad. The optimization of the dosage used for the production of MoTe2 nanotubes was obtained from the analysis of the samples that were examined in a high-resolution transmission electron microscope. The most efficient production of MoTe2 nanotubes was obtained at the range between 100 and 200 Mrad. A very typical characteristic was obtained for rotated structures with angles of 4, 5, 7, 8, and 12° observed in the diffraction pattern for MoTe2.
