Neste trabalho é discutido o espalhamento inelástico da luz por portadores no plasma simples em semicondutores. Calculamos a seção de choque do espalhamento Raman, a qual está diretamente relacionada, via teorema de flutuação-dissipção, com a função dielétrica do sistema. Nossos cálculossão comparados com resultados experimentais do GaAs nos quais são evidenciados o amortecimento de Landau.
