Exciton Radiative Lifetimes in Hexagonal Diamond Ge and SixGe1–x Alloys

open access: yesAdvanced Optical Materials, EarlyView.
Strong room‐temperature photoluminescence reported in hexagonal Ge conflicts with theory predicting a nearly dark band edge. First‐principles calculations of excitonic radiative lifetimes fill a key gap in this debate, showing that pristine hexagonal Ge remains intrinsically weakly emissive, while Si alloying only modestly shortens the lifetime and ...

A theory of the quasi-static world

Object recognition supported by user interaction for service robots, 2003
We present the theory behind a novel unsupervised method for discovering quasi-static objects, objects that are stationary during some interval of observation within image sequences acquired by any number of uncalibrated cameras. For each pixel we generate a signature that encodes the pixel's temporal structure.
