Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

A scheme for the remote sensing of terahertz waves over distances of tens of metres could have important applications in security and biology. Xi-Cheng Zhang from the Rensselaer Polytechnic ...

Abstract: Silicon single-photon avalanche diodes (SPADs) are nowadays a solid-state alternative to photomultiplier tubes (PMTs) in single-photon counting (SPC) and time-correlated single-photon ...

We directly demonstrate, for the first time, the small pixel effect in an amorphous photoconductor by measuring the intrinsic transient response of an amorphous selenium (a-Se) photoconductor pixel of ...
