Full Physical Modeling of EM Signals in a Photon Nano-Sensor Platform

Breakthroughs in photon detection devices will have a profound impact for measurement capabilities across a wide range of fields in imaging and sensing. We present recent developments in circuit layout design in the context of photon nano-sensors on a CMOS platform using full physical EM modeling. Characterizing and optimizing the transmission of signals in electrodes connecting carbon nanotube sensors to integrated circuits is crucial in the design of single or low-count photon detectors. Our approach is to use the ARTEMIS code for microelectronics to perform full physical modeling of signals to help in the design process. ARTEMIS is an extreme-scale, GPU-accelerated software framework for modeling electromagnetic wave propagation in microdevice circuitry. Using ARTEMIS we are able to model a wide range of geometrical configurations and material properties which will in turn inform proper device fabrication specifications.
