Transient and steady-state dark current in amorphous selenium avalanche radiation detectors

Kabir M.Z., Imam S.-A., Concordia University, CA

Amorphous selenium (a-Se) is currently the only commercially viable X-ray photoconductor in direct conversion detectors. However, the a-Se detector is not perfect and it has low conversion gain (X-ray to free electron-hole pair, EHP, generation) [...]

Plasmonic Enhanced Chiral Metamaterials

Alali F., Kim Y.H., Furlani E.P., University at Buffalo, US

Metamaterials are artificial materials that are engineered to produce various interesting phenomena such as negative refractivity and sub-diffraction-limit imaging. The majority of metamaterials for THz applications have been fabricated using “top-down” techniques. These methods tend [...]
