The dependence of hydrogen flux and substrate temperature during implantation on the smart-cutprocess in GaAs have been investigated in this paper. The lattice disorder in the samples was studied by ion beam analysis. It was found that both the flux

The quantum dot (QD) composition, growth methods, and implant conditions are expected to play a major role in the interdiffusion of the QDs. In this work, interdiffusion process in In 0.5 Ga 0.5 As QDs caused by ion implantation and subsequent anneal

We present the characteristics of an ion beam analysis facility based on a fully computer controlled 2 MV TandetronTM commissioned in 2002. The terminal voltage temperature stability is measured using the 3036 keV 16O(α,α)16O resonance. A microbeam

Antimony implants at 40 keV and at a dose of 4 × 1014 cm−2 have been characterized for their potential use in n-type shallow junction formation. The electrical characterization was done using sheet resistivity and Hall effect measurements. High el

We have determined with infrared spectroscopic ellipsometry how the nature of the interface between a thin polyldimethyl siloxane) (PDMS) coating and its substrate affects the rate of PDMS crosslinking reactions. Reactions between vinyl (-CH=CH 2 ) e

The value of the minimum detectable mass of an irregularity, which will change the neutron macroscopic cross section of a biological matrix by 1%, has been calculated by using neutron transmission technique. The biological matrices selected were ones

The elemental analysis method presented is based on the change in the neutron macroscopic cross section of an object due to the introduction of impurities. Equations have been derived to calculate the minimum detectable mass and length fractions of t
