Spectral distribution of Fe2+ photoionization cross section in InP:Fe
Description
Measurements of Fe2+ (5E) photoionization cross section in InP at 800K, using constant current photoconductivity technique, were done. The spectrum presents a threshold energy of ∼ 0,65 eV due to the transition from Fe2+ charge state, in the ground state, to Fe3+ with an electron emission for the minimum conduction band. In the measurement of photoluminescence at ∼ 20K, a wide emission of Fe complexe with the strong lattice interaction. In order to analyse the experimental data of Fe2+ cross section in InP, a theoretical model was used. (M.C.K.)

Foram feitas medidas de secao de choque de fotoionizacao de Fe2+ (5E) em InP, a 800K, utilizando a tecnica de fotocondutividade a corrente constante. O espectro apresenta um limiar em ∼ 0,65 eV, atribuida a transicao de estado de carga Fe2+, no nivel fundamental para Fe3+ com a emissao de um eletron para o minimo da banda de conducao. Na medida de fotoluminescencia, a ∼20K, observamos uma banda de emissao larga, a qual atribuimos a recombinacao envolvendo complexo de Fe com forte interacao com a rede. Para analisar os dados experimentais de secao de choque de Fe2+ em InP, utilizou-se um modelo teorico. (autor)Files
