Study of the thermally processed lanthanum hexaboride surface
We study the possibility to grow lanthanum oxide (La 2 O 3 ) on the surface of lanthanum hexaboride (LaB 6 ) with (100)- and (100/110)-orientation in conditions of thermal annealing, in order to produce a metal-oxide-metal structure. Electron microscopic images, X-ray and optical spectra revealed a...
