Twin-Free GaAs Nanosheets

10 nanolasers and LED applications. 11 GaAs nanostructures (e.g., nanowires and 12 nanosheets) with high surface-to-volume 13 ratios, however, suffer from high surface 14 state densities and high surface recombina15 tion velocities, which typically limit their 16 optoelectronic device performance. Passiva17 tion of GaAs nanostructures has been widely 18 studied in the literature, including clad...

Twin-free GaAs nanosheets by selective area growth: implications for defect-free nanostructures.

Highly perfect, twin-free GaAs nanosheets grown on (111)B surfaces by selective area growth (SAG) are demonstrated. In contrast to GaAs nanowires grown by (SAG) in which rotational twins and stacking faults are almost universally observed, twin formation is either suppressed or eliminated within properly oriented nanosheets are grown under a range of growth conditions. A morphology transition i...

Self-replicating twins in nanowires.

Based on molecular-dynamics simulations validated with quantum-mechanical calculations, we predict that (111) twin planes in a [111]-oriented GaAs nanowire attain attractive interactions mediated by surface strain. This gives rise to a self-replication mechanism that continuously generates a twin superlattice in a nanowire during growth. We demonstrate significant implications of the twin-twin ...

Electrical and optical characterization of surface passivation in GaAs nanowires.

We report a systematic study of carrier dynamics in Al(x)Ga(1-x)As-passivated GaAs nanowires. With passivation, the minority carrier diffusion length (L(diff)) increases from 30 to 180 nm, as measured by electron beam induced current (EBIC) mapping, and the photoluminescence (PL) lifetime increases from sub-60 ps to 1.3 ns. A 48-fold enhancement in the continuous-wave PL intensity is observed o...
