Chalcopyrite CuFeS(2) nanocrystals with a diameter of 6.4 nm were synthesized using a facile solution-phase method. Due to quantum confinement, the CuFeS(2) nanocrystals exhibit a maximum ZT value of 0.264 at 500 K, which is 77 times the value of bulk chalcopyrite.
采用简便的溶液法合成了直径为 6.4nm 的黄铜矿 CuFeS2 纳米晶体。由于量子限域效应,CuFeS2 纳米晶体在 500K 时表现出最大的 ZT 值 0.264,是块体黄铜矿的 77 倍。
