The optical and electrical properties of Non-tapered InN nanorods grown by plasma-assisted MOCVD

ORAL

Abstract

We report the non-tapered InN nanorods grown by plasma assisted metal-organic vapour deposition (MOCVD) methods. By carefully using RF plasma techniques, we were able to grow InN nanorods without NH3 at below decomposition temperature. The optical and structural qualities were evaluated by temperature dependent photoluminescence (PL) and current-voltage measurement. The PL revealed the low intrinsic carrier concentration and high structural quality of the InN nanorods. The conductance measurement, via nanoprobe system, agreed with the observed PL behaviors. The detail experimental results and their analysis will be discussed in the presentation.
