GaAs/AlGaAs Nanowire Photodetector [PDF]

open access: yesNano Letters, 2014
We demonstrate an efficient core-shell GaAs/AlGaAs nanowire photodetector operating at room temperature. The design of this nanoscale detector is based on a type-I heterostructure combined with a metal-semiconductor-metal (MSM) radial architecture, in which built-in electric fields at the semiconductor heterointerface and at the metal/semiconductor ...

Sharp interfaces in p+-AlGaAs/n-GaAs epitaxial structures obtained by MOCVD

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014
The complexity of forming sharp and high-quality boundaries in p+AlGaAs/n-GaAs systems by MOCVD method is caused by differing on 80–120°С optimal crystallization temperature of GaAs layers and n-AlGaAs solid solutions.

Thermal stability of Al/AlGaAs and Al/GaAs/AlGaAs (MBE) Schottky barriers

open access: yesElectronics Letters, 1993
Outstanding stability has been observed in Al/Al/sub x/Ga/sub 1-x/As and Al/GaAs/Al/sub x/Ga/sub 1-x/As (x=0.25) Schottky barriers prepared by depositing Al in situ by MBE on annealing up to 400 degrees C. Conventionally evaporated barriers have been fabricated and compared with epitaxial ones.
