A Catalyst-free Approach to Prepare Nano to Microstructures of GaN from a Single Molecular Complex Precursor
Article
Full-text available
  • Jul 2009
Well-organized nano- to micron-sized GaN materials have been successfully grown on Si (100) substrates from a single molecular complex precursor, under a flow of ammonia gas, by altering the reaction parameters. Four important parameters [reaction temperature, pressure, mode of heating, and type of sample holder] have been altered one by one in ord...

... major impact on GaN growth was studied at the 800 and 1000 • C, Samples A and B, respectively. Fig. 1 shows field emission scanning electron microscopy (FE- SEM) images of Sample A prepared at 800 • C under a constant ammonia flow of 200 sccm for 3 hrs. Based on these images, Sample A is composed of high-densities single-crystalline GaN nanoparticles that are randomly distributed over the whole area for the sample. The aver- ages sizes ...

Investigation of gold/GaN nanorod arrays for hypersonic detection: The effect of periodicity
Article
Full-text available
  • Oct 2015
Gold nanodisk arrays on the upper surface of GaN nanorods were developed with the aim of achieving hypersonic imaging with a detection frequency above 10 GHz. In this paper, we report the interesting phenomenon that the hypersonic signal detected by a single gold nanodisk in this structure might be dependent on the array periodicity and rod length....
