We report GaN high-electron-mobility transistors (HEMTs) with a thick (7.7 µm) GaN buffer on a Czochralski low resistivity Si (LRS) substrate. The GaN HEMTs exhibit high performance for both radio-frequency (RF) amplification and power conversion.

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

Enhancement‐mode AlGaN/GaN HEMTs on silicon substrate
High performance enhancement-mode AlGaN/GaN HEMTs (E-HEMTs) were demonstrated with samples grown on low-cost silicon substrate for the first time. The fabrication process is based on fluoride-based plasma treatment of the gate region and post-gate ...

Hydrodynamische Modellierung von AlGaN/GaN HEMTs
S.273-276For the needs of high electron mobility transistors (HEMTs) optimization a reliable software simulation tool is required. Due to the high electric field in the device channel a hydrodynamic approach is used to properly model the electron ...

The 4R principle—Resilience, Repairability, Recyclability, and Renewability—enables sustainable liquid‐metal transistors. LM materials provide stretchable, damage‐tolerant architectures, allow rapid circuit repair, permit full material recovery through dissolution, and support renewable fabrication cycles, forming a closed‐loop pathway toward ...

Investigations on Driver and Layout for Paralleled GaN HEMTs in Low Voltage Application
Gallium nitride is becoming more popular in low-voltage applications. Gallium nitride (GaN) high electron mobility transistors (HEMTs) has positive temperature feature. It makes parallel application feasible for GaN HEMTs. Meanwhile, paralleled GaN HEMTs

Carrier Transport and Electrical Bandgaps in Epitaxial CrN Layers
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.
