density of quantum states in periodical structures
... New quantum effects have been studied in thin nanograting layers. Nanograting on the surface imposes additional boundary conditions on the electron wave function and reduces the density of states. When the dimensions of the nanograting are close to the De Broglie wavelength the density of states red ...
