Impact of Polarization Charges on Threshold Voltage and Band Offset in AlGaN/GaN Heterostructures

open access: yesphysica status solidi (a), Volume 223, Issue 7, 7 April 2026.
The threshold voltage for the two‐dimensional electron gas of GaN‐based heterostructures is analyzed by considering the thickness of the polarization charge region at a semiconductor surface and interface. The proposed model gives the threshold voltage agreed with experimental results.

Carrier Transport and Electrical Bandgaps in Epitaxial CrN Layers

open access: yesAdvanced Electronic Materials, Volume 12, Issue 8, 20 April 2026.
ABSTRACT The transport properties and electrical bandgap of nominally undoped ≈$\approx$75‐nm‐thick CrN layers simultaneously grown on AlN(0001) and AlN(112¯$\bar{2}$2) templates using plasma‐assisted molecular beam epitaxy are investigated. The layers grown on AlN(0001) and AlN(112¯$\bar{2}$2) exhibit (111) and (113) surface orientations, respectively.

First‐Principles Study of Structural, Elastic, and Piezoelectric Properties of Wurtzite Superlattice ScxAl1−xN, ScxGa1−xN, and ScxIn1−xN Alloys

open access: yesphysica status solidi (b), Volume 263, Issue 4, April 2026.
This study investigates the structural, elastic, and piezoelectric properties of Sc‐doped wurtzite nitrides using first‐principles calculations. A strong compositional dependence of elastic and piezoelectric coefficients is observed, with significant nonlinearities providing insights into the tunability of these materials for piezoelectric applications.

Systematic Study of Fermi‐Level Pinning at Crystalline Metal/GaN Interfaces: First‐Principles Calculations and Diode Characterization

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...
