摘要:
Provided is a Si—Ge laminated thin film including at least one Si layer and at least one Ge layer, which are alternately laminated on a substrate (1). A Si layer (31) and a Ge layer (22) each have a thickness in a range of 5 to 500 nm. The Si layer (31) is amorphous and only the Ge layer (22) is crystallized. An average crystallite size of Ge in the Ge layer (22) is 20 nm or less.
