The discovery of three dimensional topological insulators opens a new category of quantum systems characterized by a gapless spin-momentum locked Dirac-like surface state in the bulk band gap protecte
The radiation domain of extreme ultraviolet(EUV)has great potential in science and technology in photolithography,astrophysics,photoelectron spectroscopy,etc..
Complex oxides exhibit a wealth of physical properties,such as(anti-)ferromagnetism,(anti-)ferroelectricity,piezoelectricity and superconductivity.And fertile novel phenomena emerge at the interfaces
