Modulation magnesium-doping in AlGaN/GaN superlattices

Low resistivity of p-type Mg-doped AlGaN/GaN superlattices (SLs) is demonstrated. The resistivity of the SLs is less than 0.6 Omega .cm. and the measured hole concentration is higher than 1x10(18)cm(-3). The resistivity of SLs is much lower, and the hole concentration of SLs is much higher, than that of bulk GaN and AlGaN, The electrical properties of the SLs are less sensitive than the conventional bulk lavers.
