Amorphous carbon (a-C) nanoclusters were synthesized by the implantation of carbon ions (C-) into thermally grown silicon dioxide film (-500 nm thick) on a Si (100) wafer and processed by high temperature thermal annealing. The carbon ions were impla

Carbon‐based nanocrystals, formed in silica by low‐energy carbon implantation and subsequent thermal annealing, have been previously reported, but ambiguities as to the equilibrium morphology and its relationship to the source of photo luminescen

Compact active interrogation sources are being developed that use low‐energy (kilovolt) nuclear reactions to produce high‐energy (megavolt) neutrons or gamma‐rays. We are evaluating target materials for these interrogation sources by performing

Irradiation of a single biological cell, instead of a whole tissue, with ions in a known number and position, is a powerful means to study very low dose biological effectiveness. Present methods employ accelerated ion beams which are 1) either collim

Reduction of metallic contamination during ion implantation is becoming increasingly critical for device performance. Modern implanters are therefore, being developed with novel beamline coating materials and optics to keep sputtered contamination to

Ion induced electron emission (IIEE) from solid surfaces is one of the fundamental processes with ion beam applications. The different IIEE yields from different surfaces such as Si, SiO2, metals and photoresist (PR) may cause charging and damage the

Nuclear Reaction Analysis (NRA) using the 19F(p,αγ)16O resonance reaction is a powerful method of fluorine depth profiling. We have used this method to study the fluorine uptake phenomenon in mineral flint, which could potentially develop into a me
