title: Fabry-Perot cavity oscillations of an Al(x)Ga(1-x)As photoluminescence spectrum.
abstract: When the GaAs substrate of a 5-microm Al(x)Ga(1-x) film is removed by chemical etching, oscillations in the film-layerformed Fabry-Perot cavity are observed in the low temperature photoluminescence spectrum.
