In this paper, we proposed near-infrared spectroscopy based on a Si photodetector equipped with a gold grating and extended the measurable wavelength range to cover 1200−1600 nm by improving a spectrum derivation procedure. In the spectrum derivati

Silicon-based infrared photodetector is proposed using an organic nano-dot array covered with an Au thin film. The nano-dots were self-assembled structures composed of crystalline CuPc and PTCDA organic semiconductors, and they enhanced the absorptio

We have proposed an electrical shutter operation of a nano-antenna infrared photodetector using Schottky barrier height (SBH) modulation, where the SBH is modulated by a reverse bias voltage V b applied to the detector. The inhomogeneity of the Schot

This paper reports on Signal Noise ratio (S/N) improvement of an Au/Si nano-antenna photodetector by converging light onto a small device area. The infrared light energy was efficiently absorbed by Au nano-antenna, and was transduced to photocurrent

An infrared photo-detector (IR-PD) using self-assembled organic crystalline arrays has been reported [1]. Since such structure was found to have an activation energy as large as 0.40 eV, Mid- to Near- Infrared light can be detected. In this paper, we
