1. Mai 2024 · Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ from those of larger particles via quantum mechanical effects. They are a central topic in nanotechnology and materials science.
29. Apr. 2024 · Semiconductor lasers use the optical properties of semiconducting materials to produce coherent light. Electrons and their positive-charge counterpart called holes are injected into an...
6. Mai 2024 · Laser. In 2014, a CO 2 infrared laser was used to produce patterned porous three-dimensional laser-induced graphene (LIG) film networks from commercial polymer films. The resulting material exhibits high electrical conductivity and surface area. The laser induction process is compatible with roll-to-roll manufacturing processes.
Vor 3 Tagen · Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, chemical vapor deposition (CVD) and high-pressure carbon monoxide disproportionation (HiPCO).
8. Mai 2024 · The Brightest Semiconductor Laser Ever: Photonic Crystals Enable Tiny Lasers to Melt Steel Abstract: IN 2016, THE JAPANESE GOVERNMENT ANNOUNCED a plan for the emergence of a new kind of society. Human civilization, the proposal explained, had begun with hunter-gatherers, passed through the agrarian and industrial stages, and was fast approaching the end of the information age.
26. Apr. 2024 · Semiconductor lasers with high-performance characteristics are integral components in the operation of PICs. Nevertheless, the linewidth of conventional semiconductor lasers ranges from...
7. Mai 2024 · Semiconductor laser diodes (LDs), with merits of little volume, lightweight, low power consumption, ease of modulation, and high data rates, are great candidates for space laser communications. However, operating in a radiation environment can result in various damages to LDs.
