PbSe quantum dots grown in a high-index low-melting-temperature glass for infrared laser applications [PDF]

, 2013
PbSe quantum dots (QDs) were grown in high-refractive-index low-melting-temperature lead-phosphate glass. QDs with various sizes ranging from 2 nm to 5.3 nm were grown by controlling the growth parameters, heat-treatment temperature and time.

Quantum-dot devices and Quantum-dot Cellular Automata

Journal of the Franklin Institute, 1997
We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA).

Analysis of As/GaAs quantum dot solar cells using Suns-Voc measurements [PDF]

, 2014
The performance of InAs/GaAs quantum dot solar cells was investigated up to an optical concentration of 500-suns. A high temperature spacer layer between successive layers of quantum dots was used to reduce the degradation in the open circuit voltage ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Investigation of carbon nanotube quantum dots connected to ferromagnetic leads [PDF]

, 2015
The implementation of ferromagnetic contacts in complex nanoelectronic devices, e.g. in spin-valves bears great potential for applications and fundamental investigations. Spin-valves are structures with two magnetic contacts and a non-magnetic medium (
