Abstract

Polarity-dependent homo-epitaxy on (0001)-Zn and (000 [1 with combining macron] )-O surfaces of cleaved ZnO microwires was investigated by in situgrowth in ESEM and DFT simulations. ZnO monomers adsorption, adatoms desorption and chemisorption were simulated to understand the explicit mechanism.
