Paper Abstract

Position controlled InN nanocolumns were fabricated by electron-cyclotron-resonance plasma-excited molecular beam epitaxy (ECR-MBE) on hole-patterned GaN template by focused ion beam (FIB). Dependences of morphological changes in InN nanocolumn on V/III ratio and hole size were investigated. It is found that growth with a higher V/III ratio and a larger hole size resulted in the multiple formation of InN nanocolumns in one hole. By varying the hole density on the GaN template, we succeeded to change the density of InN nanocolumn by one order of magnitude from about 100/μm2 to 9/μm2. InN nanocolumn showed luminescence with peak energy of 0.74 eV by cathodoluminescence measurement.
