Determination of the optimal shell thickness for self-catalysed GaAs/AlGaAs core-shell nanowires
R. Songmuang, Le Thuy Thanh Giang, J. Bleuse M. Den Hertog +2
We present a set of experimental results identifying various effects that govern the carrier dynamics of self-catalyzed GaAs/AlGaAs core-shell nanowires (NWs) grown by molecular be…
Residual strain and piezoelectric effects in passivated GaAs/AlGaAs core-shell nanowires
Moïra Hocevar, Le Thuy Thanh Giang, Rudeesun Songmuang +5
We observe a systematic red shift of the band-edge of passivated GaAs/Al0.35Ga0.65As core-shell nanowires with increasing shell thickness up to 100 nm. The shift is detected both i…
Intrinsic limits governing MBE growth of Ga-assisted GaAs nanowires on Si(111)
Le Thuy Thanh Giang, C. Bougerol, H. Mariette +1
Diffusion-enhanced and desorption-limited growth regimes of Ga-assisted GaAs nanowires were identified. In the latter regime, the number of vertical NWs with a narrow length distri…
