Özet
The nitrogen-polar AlGaN structure is expected to have higher carrier density when it is doped with semiconductor atoms of silicon (Si) or germanium (Ge) and noble metals of palladium (Pd) or platinum (Pt). So, the metal-polar AlGaN electronic devices offer various advantages, such as high breakdown voltage and high-temperature operation. A comprehensive investigation on hydrogen grabbing towards formation of hetero-clusters of AlGaN–H, Si–AlGaN–H, Ge–AlGaN–H, Pd–AlGaN–H, Pt–AlGaN–H was carried out using DFT computations at the CAM–B3LYP–D3/6-311+G(d, p) level of theory. The notable fragile signal intensity close to the parallel edge of the nanocluster sample might be owing to silicon or germanium binding induced non-spherical distribution of Si–AlGaN or Ge–AlGaN hetero-clusters. However, a considerable deviation exists from doping atoms of palladium or platinum as electron acceptors …
