“…At normal temperature and pressure, it crystallizes in a hexagonal close packed wurtzite structure [4] and belongs to the P6 3 mc (C 4 6V ) space group [5]. The CdSe single crystal has captured significant interest due to its high potential for room temperature nuclear radiation detectors [6,7] and nonlinear optical devices [8][9][10][11][12][13]. Many methods, such as the temperature gradient solution zoning technique (TGSZ) [14], chemical vapor transport method (CVTM) [15], solution growth [16], melt-growth [17] and solid-state re-crystallization (SSR) [18], etc., have been used for CdSe single crystal growth.…”
