Intersubband photoconductivity of self-assembled InAs quantum dots embedded in InP
Författare
Summary, in English
In this article, we present the results from photoconductivity measurements in the infrared spectral region (3-10 mum) on ensembles of self-assembled InAs quantum dots embedded in a matrix of InP. In the spectral distribution of the photocurrent, peaks are observed which we interpret in terms of transitions from the dots' ground- and first-excited states to the conduction band of the dots/matrix. Furthermore, we have calculated the expected photoresponse and found it to be in qualitative agreement with our experimental data.
