Abstract

Abstract

Reduced graphene oxide-based field effect transistor is fabricated and tested for detection of UV photons in 100-280 nm range. A novel technique is used for reduction of Graphene oxide. The fabricated device showed promising response to UV photons in terms of resistance change in rGO

Abstract

Abstract

Graphene is an ideal detector material that offers absorption across a large spectral range. Yet, speed and high quantum efficiency are a challenge. In this review we discuss plasmonics as a solution to achieve bandwidths in excess of 100 GHz in combination with high responsivities.

ThE1.3 - FIRST PRINCIPLES INVESTIGATION INTO GRAPHENE-PBSE MIDWAVE IR (MWIR) PHOTODETECTOR PHYSICS

Abstract

Abstract

Using Density Functional Theory (DFT) based simulations we investigate new designs of PbSe-Graphene MWIR detector and their physics. These detectors have three possible distinct modes of operation depending on the interface design, and show promise for scalable, high operating temperature, low noise, CMOS integrable photodetectors.

ThE1.4 - NANOSCALE ISOTOPIC IMAGING BY EXTREME ULTRAVIOLET LASER ABLATION MASS SPECTROMETRY

Abstract

Abstract

We report on the development of an extreme ultraviolet laser ablation time-of-flight mass spectrometer for high resolution elemental and isotopic analysis, and show how it compares to more developed analytical techniques such as secondary ion mass spectrometry.
