Abstract:
Provided is an epitaxial substrate for semiconductor elements which suppresses an occurrence of current collapse. The epitaxial substrate for the semiconductor elements includes: a semi-insulating free-standing substrate formed of GaN being doped with Zn; a buffer layer being adjacent to the free-standing substrate; a channel layer being adjacent to the buffer layer; and a barrier layer being provided on an opposite side of the buffer layer with the channel layer therebetween, wherein the buffer layer is a diffusion suppressing layer that suppresses diffusion of Zn from the free-standing substrate into the channel layer.

Claim (Index 3):
The epitaxial substrate for the semiconductor elements according to  claim 1 , wherein\n said group 13 nitride layer is either of a multi-layered buffer layer, which is formed by laminating two or more group 13 nitride layers having different compositions, at least one of said two or more group 13 nitride layers being doped with C at a concentration of 1\u00d710 18  cm \u22123  or more, or a composition gradient buffer layer formed of group 13 nitride containing two or more group 13 elements each having an existence ratio being changed in a thickness direction.
