Production of Nitrogen Acceptors in ZnO by Thermal Annealing

Annealing behaviour of high-dose-implanted nitrogen in InP

Concentration profiles of nitrogen in vacuumannealed pand n-type single-crystal (1 0 0) InP implanted with 1]101630 keV 15N` ions cm~2 have been studied by Secondary Ion Mass Spectrometry (SIMS) and Nuclear Resonance Broadening (NRB) techniques. Damage induced by the nitrogen implantation was studied by Rutherford Backscattering Spectrometry (RBS) and channeling. Annealing the samples led to lo...

Effect of Laser Annealing on Optical Properties of Ion-Implanted ZnO Nanorods

We report on the demonstration of the effectiveness of nanosecond laser annealing on optical properties of phosphorus ion (P)-implanted ZnO nanorods (NRs). Vertically-alligned ZnO NRs have been synthesized by nanoparticle-assisted pulsed laser deposition (NAPLD) on c-plane sapphire substrates. The pre-laser annealing was performed with the third harmonic (355 nm) of a Qwitched Nd:YAG laser at a...
