A team led by Ivan Shorubalko from the Transport at the Nanoscale Interfaces laboratory is working on miniaturized IR detectors made of colloidal quantum dots. The words "quantum dots" do not ...

Quantum dots (QDs) and nanocrystals are emerging as significant materials in the field of infrared photodetection. Their unique properties, such as tunable band gaps and high electron mobility ...

The proposed nanowire structure consists of a GaAs tip with a tip angle as small as 4° and a quantum dot positioned ... have created a mid-infrared semiconductor detector that operates at room ...

Direct comparative testing indicates that the HGFET can detect weak infrared radiation at 0.46 nW cm −2 levels, thus making this detector much more sensitive than the commercial and reported ...

Recently, the group of Prof. Labao Zhang of Nanjing University, together with the group of researcher Haiyong Gan of the National Institute of Metrology, China, have developed a new thermal radiation ...
