We elaborate a quadratic nonlinear theory of plural interactions of growing space charge wave (SCW) harmonics during the development of the two-stream instabili
The carrier mobility of two-dimensional tetragonal carbon allotrope (T-CA) from porous graphene is investigated by first-principles calculations.T-CA can be con
Bi2Te3 thin films and GeTe/B2Te3 superlattices of different thicknesses are prepared on the silicon dioxide substrates by magnetron sputtering technique and the
Oxide semiconductor SrTiO_3 single crystals are exposed to a reducing atmosphere H_2/N_2 to induce the reduction of Ti~(4+) to Ti~(3+) and the release of oxygen
A tunable absorber,composed of a graphene ribbon on two layers of TiO2-Au between two slabs of dielectric material all on a metal substrate,is designed and nume
