We explore the concepts of physics of light, heat, work, and photoconversion. Heat is described as energy transfer by conduction or radiative transfer, as opposed to being a "hot" body. Light is described as having both kinetic and potential energy. The historical context separating concepts of...
Light is the only energy source in photocatalytic CO2 reduction reactions. In the semiconductor-based photocatalysts, photogenerated electrons and holes can only be excited when the photon energy is greater than the band gap of semiconductors. The photon energy (indicated by the wavelength of incident...
Green photonics is presently thought to be a major sunrise direction of R+D with huge impact in particular on communication systems, like workstation clusters or supercomputers. Their energy consumption is now approaching or already surmounting 500 MW for new installations. Most of their energy is ...
in this study, compared with the data found in the literature27,28, is its relatively low flat-band potential value which was determined equal to −0.92 V vs. NHE (Supplementary Fig.8) and a rather low energy of the Fermi level with respect to the valence band edge—the energy ...
Similarly, interface engineering was applied to either passivate interface defects or establish proper energy barriers at the interface5,22,23. Finally, judicious selection of precursors and anionic species was found to be efficient in alleviating hysteresis problems due to ionic species5,6,9. Defects...

far-infrared electromagnetic shielder. This type of "FIRTC" is expected to be applied to the technical fields that are beyond the reach of traditional visible ITO, such as photodetectors, invisible sensors, etc. This will lead to more new research ...
Propagation of light refers to the manner in which an electromagneticwave transfer it’s energy from one point to another. Threemain processes generally occur when light passes between boundaries from one medium to another: Transmission Reflection ...
The latter interacts with quasi-particle excitations at an energy of ~ωH,1, which amplifies the THz-MDCS sideband peaks at frequencies ~2ωH,1 (Fig. 3e). This amplification is at the expense of the Higgs mode peak at ωH,1, which dominates in regime (ii) (Fig. 3f). To further ...
to the value of parabolic approximation. But as seen from the energy evolution in Fig.3e, phonon does not reduce the carrier energy significantly. If impact ionization occurs, the number of holes doubles as in the process new electron and hole generate. The carrier will lose its energy. ...
