各种不同的可能的施主和受主杂质已被注入GaN中,并退火至1450 °C。S+和Te+产生的峰值电子浓度约为1.5 ×1018 cm−3,远低于Si+的峰值电子浓度。 Mg离子注入样品产生p型导电性,而Be+和C+离子注入样品仍保持n型导电性。对于1450 °C退火,没有观察到任何注入物质的再分布。与更常用的1100 °C退火相比,高剂量(5×1015 cm−2)Si+注入GaN的1400 °C退火实现了更有效的损伤去除。
A variety of different possible donor and acceptor impurities have been implanted into GaN and annealed up to 1450 °C. S+ and Te+ produce peak electron concentrations ⩽5×1018 cm−3, well below that achievable with Si+. Mg produces p-type conductivity, but Be+- and C+- implanted samples remained n type. No redistribution was observed for any of the implanted species for 1450 °C annealing. Much more effective damage removal was achieved for 1400 °C annealing of high-dose (5×1015 cm−2) Si+ implanted GaN, compared to the more commonly used 1100 °C annealing.
