A team led by DGIST professor Seo Dae-ha has developed an experimental strategy to control and observe the chemical reaction of a single nanocatalyst using an optical microscope. The work is expected to contribute to catalyst ...
Tiny crystals, known as quantum dots, have enabled an international team to achieve a quantum efficiency exceeding 100 percent in the photocurrent generated in a hybrid inorganic-organic semiconductor.
A semiconductor is a material whose conductivity lies somewhere between that of a conductor and an insulator. This property allows semiconductors to serve as the base material for modern electronics and transistors. It is ...
You don't normally want to mix electricity and water, but electricity behaving like water has the potential to improve electronic devices. Recent work from the groups of engineer James Hone at Columbia and theoretical physicist ...
When an optical pulse train is delivered, two-photon absorption (TPA)-induced pumping causes considerable and quick gain and phase shifts in the carrier reservoir semiconductor optical amplifier (CR-SOA).
The effect of temperature on the performance of the semiconductor optical amplifiers (SOAs) is an important research point. Amer Kotb and his colleagues from the Changchun Institute of Optics, Fine Mechanics and Physics of ...
Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up ...
Atomically thin semiconductors such as molybdenum disulfide and tungsten disulfide are promising materials for nanoscale photonic devices. These approximately 2D semiconductors support so-called excitons, which are bound ...
Information in computers is transmitted through semiconductors by the movement of electrons and stored in the direction of the electron spin in magnetic materials. To shrink devices while improving their performance—a goal ...
New theoretical analysis considers cases where the electrons are allowed to exist beyond the boundaries of semiconducting quantum wires—with important implications for their performance
