Generation and propagation of super-high-frequency bulk acoustic wave in GaAs
Diego H. O. Machado, Antonio Crespo-Poveda, Alexander S. Kuznetsov +3
Coherent super-high-frequency (SHF) vibrations provide an excellent tool for the modulation and control of excitations in semiconductors. Here, we investigate the piezoelectric gen…
Electrical suppression of spin relaxation in GaAs(111)B Quantum Wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
Spin dephasing via the spin-orbit interaction (SOI) is a major mechanism limiting the electron spin lifetime in III-V zincblende quantum wells. The dephasing can be suppressed in G…
Electric control of spin transport in GaAs (111) quantum wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
We show by spatially and time-resolved photoluminescence that the application of an electric field transverse to the plane of an intrinsic GaAs (111) quantum well (QW) allows the t…
Sidewall quantum wires on GaAs(001) substrates
Paul L. J. Helgers, Haruki Sanada, Yoji Kunihashi +2
We study the structural, optical, and transport properties of sidewall quantum wires on GaAs(001) substrates. The QWRs are grown by molecular beam epitaxy (MBE) on GaAs(001) substr…
