Production of High-Performance CdZnTe Crystals Grown by THM for Radiation Detection Applications

Development of travelling heater method for growth of detector grade CdZnTe single crystals

“…Cadmium zinc telluride (CdZnTe) is one of the most promising room-temperature semiconductor gamma radiation detector material due to its wide energy band gap and high atomic number [1][2][3][4]. The research activities carried out on detector technology over the past few decades have showcased that CdZnTe is an excellent substitute for scintillation detectors in terms of high sensitivity, better energy resolution and high spatial resolution at room temperature [4][5][6][7].…”

“…The THM is the most successful crystal growth method that has been shown to produce detector-grade CdTe and CdZnTe crystals consistently by different industries including ACRORAD, Co., Ltd, Japan [3,4,13,[16][17][18][19]21]. The main advantage of THM is the possibility of growing crystals at lower growth temperature due to the addition of excess Te which is used as a solvent.…”
