AlScN/GaN Multichannel Heterostructures Grown by Metal–Organic Chemical Vapor Deposition

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 23, December 8, 2025.
Growth of AlScN/GaN multichannel heterostructures by metal–organic chemical vapor deposition is demonstrated for the first time. The growth of such structures is detailed through changes in growth parameters, such as the number of periods and the thickness of the channel layers, as well as structural studies.

Electrical spin injection and detection in an InAs quantum well

open access: yes, 2006
We demonstrate fully electrical detection of spin injection in InAs quantum wells. A spin polarized current is injected from a NiFe thin film to a two-dimensional electron gas (2DEG) made of InAs based epitaxial multi-layers.
