Nesse trabalho, foi investigado um novo tipo de fotodetector de radiação infravermelha baseado em pontos quânticos de submonocamada de InAs obtidos pela técnica de epitaxia por feixe molecular (MBE, Molecular Beam Epitaxy). Suas propriedades foram comparadas com as de fotodetectores de pontos quânticos de InAs convencionais obtidos pela mesma técnica de deposição, mas no modo de crescimento Stranski-Krastanov. Medidas de corrente de escuro, de ruído, de responsividade e de absorção mostraram que, dependendo da estrutura das amostras, os dispositivos com pontos quânticos de submonocamada podem ter um excelente desempenho.In this work, we investigated a new type of infrared photodetector based on InAs sub-monolayer quantum dots grown by molec...
