Two dimensional transition metal chalcogenides have multi valley structures in their energy bands, giving them electron valley degrees of freedom, making them an ideal platform for studying multi body interactions. As the main mechanism of valley depolarization, the valley scattering process of free electrons or bound excitons is crucial for exploring excited state electron phonon interactions and...
Rydberg atoms and molecules are characterized by having one or more electrons in highly excited bound states. Such atoms and molecules are said to be in “Rydberg states” and are also called “hollow” atoms and molecules. Rydberg states are useful for studying various phenomena arising in intense light–matter interaction that involve electronic excitation with an intens...
The Asia Photonics Expo (APE), as an internationally leading comprehensive brand promotion and business negotiation platform for optoelectronics, will be grandly held from February 26 to 28, 2025 at the L1 exhibition hall of the Sands Expo&Convention Centre in Singapore. As the top event in the field of optoelectronics, APE Asia Optoelectronics Expo will focus on cutting-edge innovative techno...
Of the three primary stepper motor designs — permanent magnet, variable reluctance, and hybrid — hybrid stepper motors are arguably the most popular in industrial applications, combining the best performance characteristics of permanent magnet and variable reluctance types.Hybrid stepper motors are constructed with a rotor made of two sections, or cups, with a permanent magnet between ...
One vision for computing the future is to use ripples in magnetic fields as the fundamental mechanism. In this application, magnetic oscillators can be comparable to electricity and serve as the foundation of electronic products.In traditional digital technology, this magnetic system is expected to be much faster than today's technology, from laptops and smartphones to telecommunications. In quant...
