What exactly is Tungsten Selenide
Selenide tungsten (WSe2) (type 2 d material) is a graphene type 2. Its structure is composed the the top layer of selenium/tungsten atom connections between tungstenatoms. This layer has high electrical conductivity, an atomic thickness, fast electron transfers, constraint spin and other special properties. Furthermore, two selenide-tungsten, the lowest in thermal conductivity materials, is 100000th the size of a diamond. There are many applications for tungsten selenide in chemical, biosensors and supercapacitors as well solar cells and batteries.
Research significance of photonics
Photonics, a science that examines information carrier with photons, has broad applications to semiconductor laser, new materials and optical communication devices. For the advancement of photonic technology, and for future research into the process of creating photonic devices, it is vital to understand and investigate the photonic generator process.
Tungsten Selenide In Photonic Technology
Researchers discovered that the tungsten selenide was composed of many “co-oscillations” which are sensitive and responsive to photon absorption. One of WSe2’s oscillations was chosen by the team, which was called D excitons and another pulse (1). They found that if WSe2 was exposed to two excitation pulses (1 & 2), one of these pulses was converted to an A exciton. Their sum frequency (1+2) was then changed to A D exciton with an A signal that is 20 times greater than the single resonant. SFG produces photons with a higher intensity than SHG.
These are just a few of the many benefits that advanced photonic devices have. Not only does the double resonance SFG technique provide new scientific methods for microscopic, nonlinear spectral, and optical analysis but it also allows for new nonlinear optics techniques and nonlinear optometry using two-dimensional semiconductors. These researches have the potential of bringing photonics up to a higher level, with new scientific for nonlinear spectral and microscopic methods, as well as medical care using better diagnostic tools and optical imaging equipment.
