Determination Li concentration in wide band gap SnO2
Semiconductor, using RBS technique
EMSL Project ID
15904a
Abstract
Tin Oxide has been widely used as an n-type material and very little progress has been made so far to fabricate it into a p-type material. We have recently reported that Li insertion into tin dioxide is pH dependent. As a follow up to this work we are interested in understanding how other preparatory conditions affect the dynamics of Li insertion into SnO2. That is, we want to look at the effect of; temperature, solvents, crystallite size, pH and reaction time on how much Li get incorporated into SnO2. We have synthesized SnO2 samples at different doping levels, as a function of pH, calcination temperature and using different solvents and interested in knowing how much lithium is incorporated into the SnO2 lattice. A good method that can be used to quantitatively determine this is Nuclear reaction analysis (NRA).
