采用变温霍尔效应技术研究了一种新的气相传输法生长的大直径（2英寸）n型ZnO晶锭。300 K霍尔载流子浓度和迁移率分别约为6 × 10（16）cm（-3）和205 cm（2）V-1 s（-1），峰值迁移率（50 K）约为2000 cm（2）V-1 s（-1），与东方报道的ZnO的最高值相当。主要施主的浓度约为1 × 10（17）cm（-3），能量约为60 meV，接近预期的类氢值，而总受主浓度要低得多，约为2 × 10（15）cm（-3）。光致发光测量证实了材料的高品质。(C)1998 Elsevier Science Ltd.
Large-diameter (2-inch), n-type ZnO boules grown by a new vapor-phase transport method were investigated by the temperature-dependent Hall-effect technique. The 300-K Hall carrier concentration and mobility were about 6 x 10(16) cm(-3) and 205 cm(2) V-1 s(-1) respectively, and the peak mobility (at 50K) was about 2000 cm(2) V-1 s(-1), comparable to the highest values reported in the East for ZnO. The dominant donor had a concentration of about 1 x 10(17) cm(-3) and an energy of about 60 meV, close to the expected hydrogenic value, whereas the total acceptor concentration was much lower, about 2 x 10(15) cm(-3). Photoluminescence measurements confirm the high quality of the material. (C) 1998 Elsevier Science Ltd.
