Abstract

The polymorphism of the tetrahedrally-bonded semiconductor Cu2SnSe3 can be precisely controlled via post-synthesis annealing. This experimental parameter dictates nanoscale structural disorder, modulating the charge-carrier mobility and thermoelectric efficiency. Our findings establish disorder engineering in diamond-like semiconductors as a powerful strategy to tailor and optimize their functional properties.

通过控制结构排序解锁Cu2SnSe3的热电性能

通过合成后退火可以精确控制四面体键合半导体Cu2SnSe3的多态性。这个实验参数决定了纳米级结构的无序性，调节了载流子迁移率和热电效率。我们的研究结果建立了类金刚石半导体的无序工程作为定制和优化其功能特性的有力策略。
