Studies of MBE-Grown Single and Multiple AlN/GaN Heterojunctions

by Cao Yu

This book is Yu Cao's Master dissertation under Prof. Jena's direction. The book discussed the growth of single and multiple AlN/GaN heterojunctions by Molecular Beam Epitaxy (MBE). Transport properties of single AlN/GaN heterojunctions have been studied. Record-low sheet resistance in single nitride heterojunctions have been achieved. Dominant scattering mechanisms in AlN/GaN heterojunctions are discussed with the support of experimental results. Shubnikov de-Haas oscillations have been observed for the first time in binary nitrides. In the study of AlN/GaN superlattices, theoretical calculation for subband energy is demonstrated under the approximation of using Airy function as the electron wavefunction. Acoustic phonon propagation across AlN/GaN superlattices are studied based on transfer matrix method. Transmission rate of acoustic phonons in AlN/GaN superlattices with different structures are modeled. Phonon filters and cavities are design according to this study with the support of simulations.

About the author

Cao Yu (曹禺; September 24, 1910—December 13, 1996), born as Wan Jiabao (萬家寶/万家宝), was a renowned Chinese playwright, often regarded as China's most important of the 20th century. His most well-known works are Thunderstorm (1933), Sunrise (1936) and Peking Man (1940). It is largely through the efforts of Cao Yu that the modern Chinese "spoken theater" took root in 20th-century Chinese literature.
