Proceedings Paper

Recent progress in semiconductor nanowire photodetectors for color and multispectral imaging (Conference Presentation)
Author(s): Kenneth B. Crozier

Paper Abstract

We present recent studies in which engineering the interaction between light and nanoscale materials has been pursued for applications in image sensors and in spectroscopy. In the first, we present recent work by the author and colleagues on the use of silicon [1-5] and germanium [6] nanowires for multispectral imaging. We show that their ability to support waveguide modes leads to spectrally-selective absorption properties [1]. We show that this in turn enables the nanowires to be used as filters or photodetectors for color and multispectral imaging [2-6]. [1] K. Seo et al, Nano Letters 11, 1851 (2011) [2] H. Park and K.
