Abstract

A method for fabricating a nitride semiconductor thin film includes preparing a first nitride single crystal layer doped with an n-type impurity. A plurality of etch pits are formed in a surface of the first nitride single crystal layer by applying an etching gas thereto. A second nitride single crystal layer is grown on the first nitride single crystal layer having the etch pits formed therein.
