【摘要】 本文采用水热法在430℃,以3mol%.L-1KOH作矿化剂,填充度为35%,反应时间24h,合成了Zn1-xMnxO稀磁半导体晶体。所合成晶体具有ZnO纤锌矿结构,晶面显露正极面{0001}、负极面{0001}、菱面{1011}及负菱面{1011}晶体高度为5~30μm,径高比约为2:1。X荧光能谱(EDS)显示Mn原子百分浓度为2.6%(x=0.026)。晶体呈现低温铁磁性,居里温度50K。更多还原

【Abstract】 Diluted magnetic semiconductor Zn_1-xMn_xO crystals were synthesized at 430℃ for 24h by hydrothermal method.3mol%·L^-1 KOH was used as the mineralizer,and the fill factor is 35%.The obtained crystals show a ZnO wurtzite structure,with positive polar faces {0001},negative polar faces｛0001｝,p faces ｛1011｝and-p faces ｛1011｝exposed.The height of the crystal is 5-30μm and radius-height ratio is 2:1.Mn atom concentration of 2.6%（x=（0.026）） was determined using X-ray energy dispersive spectroscopy（EDS）.The crystals show low-temperature ferromagnetism with Curie temperature of 50K.更多还原
