Spontaneous and piezoelectric polarization effects in III–V nitride heterostructures
The role of spontaneous and piezoelectric polarization in III–V nitride heterostructures is investigated. Polarization effects and crystal polarity are reviewed in the context of nitride heterostructure materials and device design, and a detailed analysis of their influence in nitride heterostructure field-effect transistors is presented. The combined effects of spontaneous and piezoelectric po...
متن کاملPseudopotential theory of dilute III–V nitrides
We review the empirical pseudopotential method and its recent applications to the III–V nitride alloys GaAsN, GaPN, GaInAsN and GaAsPN. We discuss how studies using this method have provided an explanation for many experimentally observed anomalous nitride phenomena, including sharp photoluminescence lines in dilute alloys, high effective masses, Stoke’s shift between emission and absorption in...
متن کاملPolarization-engineering in group III-nitride heterostructures: New opportunities for device design
The role of spontaneous and piezoelectric polarization in III–V nitride heterostructure devices is discussed. Problems as well as opportunities in incorporating polarization in abrupt and graded heterojunctions composed of binary, ternary, and quaternary nitrides are outlined. 1 Introduction Spontaneous polarization exists along the (0001) (metal-polar) and ð0001Þ (N-polar) directions of wurtzi...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولStudy of elastic and piezoelectric properties of two-dimensional hexagonal III-V binary compounds: First-principles calculations
In this work, using plane wave method in the framework of density-functional theory, we calculated clamped-ion and relaxed-ion elasticity, stress and strain piezoelectric independent coefficients for seven stable combinations of honeycomb monolayers XY (X:B,Al,Ga,In ; Y:N,P,As,Sb). The coefficients calculations by two methods of density functional perturbation theory (DFPT) and finite differenc...
