Biocompatible Single-Crystal Selenium Nanobelt Based Nanodevice as a Temperature-Tunable Photosensor
Figure 2
SEM, HRTEM, EDS, and XRD characterization of selenium nanobelts. ((a), (b)) SEM images of single-crystalline Se nanobelts in different magnifications. ((c)–(e)) HRTEM images taken from the middle of the Se nanobelt show that the corresponding electron diffraction pattern and its growth direction is . (f) EDS indicates the Se nanobelts with pure composition. (g) XRD pattern confirms that the Se nanobelts are trigonal structure.
