Shamir, Assaf, Amit, Iddo, Englander, Danny, Horvitz, Dror & Rosenwaks, Yossi (2015). Potential barrier height at the grain boundaries of a poly-silicon nanowire. Nanotechnology 26(35): 355201.

Author(s) from Durham


We present measurements of the potential barrier height and its dependence on grain size in poly-silicon nanowire (P-SiNW) arrays. Measurements conducted using Kelvin probe force microscopy coupled with electrostatic simulations, enabled us also to extract the density of the grain boundary interface states and their energy distribution. In addition it was shown that the barrier height scales with the grain size as the square of the grain radius.
