Superconducting nanowire single photon detectors (SNSPDs) have low dark counts, improved gain stability, and high resolution compared to traditional infrared detectors. Recent work at NIST and NASA has incorporated SNSPDs into arrays and extended the response into the mid-infrared to use for spectroscopy and hyperspectral imaging. We are developing novel methods to spectrally calibrate and measure stability of these detectors in this challenging wavelength range from 3 µm to 25 µm.

We employ molecular dynamics simulations to understand the energy transfer processes involved during the collisions of CH4 and CD4 with CH4 layered surfaces at 20 K in order to explain our experimental finding of preferential adsorption of CD4 compared to CH4. There is good agreement between our MD simulations and our experimental results.
