Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have ...
Defects often limit the performance of devices such as light-emitting diodes (LEDs). The mechanisms by which defects annihilate charge carriers are well understood in materials that emit light at red ...
LOS ALAMOS, N.M., October 7, 2019-- Los Alamos National Laboratory scientists have synthesized magnetically-doped quantum dots that capture the kinetic energy of electrons created by ultraviolet light ...
MALARGÜE, Argentina—Scientists of the Pierre Auger Collaboration announced today (Nov. 8) that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays ...
