Popis: |
Nanothin films of bismuth telluride Bi2Te3 were obtained by thermal sputtering in vacuum on a mica substrate with amorphous carbon and a copper sublayer. A sample with a specially created sharp thickness gradient was studied by transmission electron microscopy (TEM). An island-labyrinth structure of the film was revealed, with the size of islands in the range of about 7-25 nm. The film is amorphous at the beginning of the thickness gradient; in the studied regions of greater thickness, it crystallizes in the rhombohedral Bi2Te3 phase. High-resolution TEM has revealed crystallization of initially amorphous islands under the action of a focused electron beam of increased intensity in an electron microscope column. |
