Piezoresistance in defect-engineered silicon
H. Li, A. Thayil, C. T. K. Lew +5
The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a functio…
Mechanical stress dependence of the Fermi level pinning on an oxidized silicon surface
H. Li, L. Martinelli, F. Cadiz +4
A combination of micro-Raman spectroscopy and micro-XPS (X-ray photo-electron spectroscopy) mapping on statically deflected p-type silicon cantilevers is used to study the mechanic…
Exciton diffusion in WSe2 monolayers embedded in a van der Waals heterostructure
F. Cadiz, C. Robert, E. Courtade +9
We have combined spatially-resolved steady-state micro-photoluminescence (PL) with time-resolved photoluminescence (TRPL) to investigate the exciton diffusion in a WSe monol…
Anomalous temperature dependence of photoelectron charge and spin mobilities in p+-GaAs
F. Cadiz, D. Paget, A. C. H. Rowe +2
The effect of an electric field on the spatial charge and spin profiles of photoelectrons in p+-GaAs is studied as a function of lattice and electron temperature. The charge and sp…
On giant piezoresistance effects in silicon nanowires and microwires
J. S. Milne, S. Arscott, C. Renner +1
The giant piezoresistance (PZR) previously reported in silicon nanowires is experimentally investigated in a large number of surface depleted silicon nano- and micro-structures. Th…
