In the pursuit of global carbon neutrality, artificial photocatalysis offers a powerful solution to simultaneously address the issues of the greenhouse effect and energy shortage. This process involves the direct transformation of carbon dioxide (CO2) and water into useful fuels and oxygen under ambient...
laser can be coupled in, and its out-of-plane polarized component can be selectively enhanced by the scanning probe microscope (STM) driven gap mode between the gold tip and gold substrate, yielding a greater coupling efficiency with the out-of-plane transition dipole moment of dark excitons. ...
To better understand the optical properties of the PhC device, we performed numerical simulations and characterizations of the device. Figure2ashows the dispersion curves of the eight lowest energy bands (optical band structures, by the MPB band solver34) along the Γ-X line [\({{{\bf{k}}}...
The allowed conrotatory cyclobutene ring-opening has a distinctly nonplanar carbon skeleton. Classic experiments by Brauman and Archie, and by Freedman et al., placed the allowed/forbidden gap at greater than 15 kcal/mol. Wolfgang Roth proposed that a system forced to planarity might have a ...
The ions which are implanted are such that the resulting compound material has a higher energy gap than that of silicon into which they are implanted to selectively modify the emitter region so as to locally increase its energy gap. Preferred materials include carbon and nitrogen.STRAIN ROBERT J...

They are known to represent a fingerprint of the system as well as to hint the underlying nature of chemical bonds. In this work, we focus on addressing how the vibrational density of states (VDOS) of the carbon fullerene family (Cn: n = 20 → 720 atoms) evolves from the ...
amorphous silicon alloys containing oxygen, type p, with a wide range of energy and devices using the same forbidden.Wide band gap p-type amorphous silicon alloys having increased conductivities contain oxygen as a band gap increasing element. Other band gap increasing elements such as carbon can ...
