Anisotropy In a-Plane Magnesium Zinc Oxide Thin Films

Wide band gap semiconductor Zinc Oxide is of
significant interest for use in blue LED s, short
wavelength laser diodes, high temperature and power
devices, and transparent conductive oxides. Polar
c-axis oriented Zinc Oxide and its alloy Magnesium
Zinc Oxide based heterostructures and quantum wells
have been developed. These heterostructures and
quantum wells however suffer from limited quantum
efficiency due piezoelectric and spontaneous
polarization fields. The use of non-polar a-axis and
m-axis oriented films has thus gained importance for
development of high quantum efficiency structures.
The non-polar films however possess in-plane
structural, optical, electrical and acoustic
anisotropic properties. Though some of these
properties maybe advantageous for development of
novel electronic, optical and acoustic devices,
others might be detrimental to development of
non-polar heterostructures and quantum wells.
Currently, only limited information is available of
study and control of these anisotropic properties.
This book presents MOCVD growth optimization and
comprehensive characterizations of anisotropic
properties of a-plane Zinc Oxide and Magnesium Zinc
Oxide thin films.
