A new family of quaternary semiconductors Cu2ZnAS4-x and CuZn2AS4 (A = Al, Ga, In) has been synthesized in the form of wurtzite phase nanocrystals for the first time. The nanocrystals can be converted to the stannite phase via thermal annealing under a N2 atmosphere. A direct band gap in the visible wavelength region combined with a high absorption cross-section makes these materials promising for solar energy conversion applications.
首次合成了一种新型的四元半导体Cu2ZnAS4-x和CuZn2AS4（A = Al、Ga、In），其为纤锌矿相纳米晶体形式。通过在N2气氛下进行热退火，这些纳米晶体可以转变为黄锡矿相。在可见光波长区域的直接带隙与高吸收截面相结合，使得这些材料在太阳能转换应用方面具有潜力。
