Design of high-mobility p-type GaN via the piezomobility tensor
Jie-Cheng Chen, Joshua Leveillee, Chris G. Van de Walle +1
Gallium nitride (GaN) is a wide-bandgap semiconductor of significant interest for applications in solid-state lighting, power electronics, and radio-frequency amplifiers. An import…
Clarification of the Spontaneous Polarization Direction in Crystals with Wurtzite Structure
Simon Fichtner, Mohamed Yassine, Chris van de Walle +1
The wurtzite structure is one of the most frequently found crystal structures in modern semiconductors and its inherent spontaneous polarization is a defining materials property. D…
A first-principles approach to closing the "10-100 eV gap" for charge-carrier thermalization in semiconductors
Dallin O. Nielsen, Chris G. Van de Walle, Sokrates T. Pantelides +3
The present work is concerned with studying accurately the energy-loss processes that control the thermalization of hot electrons and holes that are generated by high-energy radiat…
Anisotropic-strain-enhanced hole mobility in GaN by lattice matching to ZnGeN and MgSiN
Joshua Leveillee, Samuel Ponce, Nicholas L. Adamski +2
The key obstacle toward realizing integrated gallium nitride (GaN) electronics is its low hole mobility. Here, we explore the possibility of improving the hole mobility of GaN via…
Mechanism for the decomposition of lithium borohydride
Khang Hoang, Chris G. Van de Walle
We report first-principles density functional theory studies of native defects in lithium borohydride (LiBH), a potential material for hydrogen storage. Based on our detailed…
LiH as a Li and H ion provider
Khang Hoang, Chris G. Van de Walle
We present a first-principles study of the formation and migration of native defects in lithium hydride (LiH), a material of interest in hydrogen storage and lithium-ion batteries.…
