Unlike semiconductors such as Si or GaAs, the major scattering mechanism for undoped or lightly doped samples is dislocation scattering instead of ionized impurity scattering. It was found that for GaN samples in the dislocation scattering region, the mobility is a function of the dislocation density and free carrier concentration, via a μdis ∝ √n/Ndis relationship. Temperature-variation mobility plots also indicate that a T3/2 dependence component is present, which is also attributed to dislocation scattering. © 2002 Published by Elsevier Science Ltd.||Source Title:||Materials Science in Semiconductor Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/83640||ISSN:||13698001||DOI:||10.1016/S1369-8001(02)00019-7|
