Abstract: A semiconductor structure comprises a semiconductor substrate including a first silicon substrate component having a first crystalline orientation and a second silicon substrate component over the first silicon substrate and having a second crystalline orientation different from the first crystalline orientation. The semiconductor substrate defines a trench extending through the second silicon substrate component and at least partially within the first silicon substrate component. A gallium nitride structure is disposed within the trench of the semiconductor substrate.

Abstract: Device architectures based on trapping and de-trapping holes or electrons and/or recombination of both types of carriers are obtained by carrier trapping either in near-interface deep ambipolar states or in quantum wells/dots, either serving as ambipolar traps in semiconductor layers or in gate dielectric/barrier layers. In either case, the potential barrier for trapping is small and retention is provided by carrier confinement in the deep trap states and/or quantum wells/dots. The device architectures are usable as three terminal or two terminal devices.

Abstract: An optoelectronic device may include an insulating substrate, a semiconductor channel region located on the insulating substrate, and a source region and a drain region in contact with the semiconductor channel region. A photoswitchable material may be located on the semiconductor channel region between the source region and the drain region, such that the photoswitchable material includes a first structural state based on being exposed to a first optical wavelength, and includes a second structural state based on being exposed to a second optical wavelength. The first structural state causes a first electrical current to flow between the source region and the drain region, while the second structural state causes a second electrical current to flow between the source region and the drain region.
