AlXGa1-XN SINGLE CRYSTAL AND ELECTROMAGNETIC WAVE TRANSMISSION BODY

摘要

Disclosed is an AlxGa1-xN single crystal suitable as an electromagnetic wave transmission body.  Also disclosed is an electromagnetic wave transmission body comprising an AlxGa1-xN single crystal. An AlxGa1-xN (0 -3 when at least any one high-frequency signal of 1 MHz and 1 GHz is applied under an atmosphere temperature of 25°C.  An electromagnetic wave transmission body (4) comprises an AlxGa1-xN single crystal (2) having one main plane (2m), wherein the AlxGa1-xN single crystal (2) has a dielectric loss tangent of not more than 5 × 10-3  when at least any one high-frequency signal of 1 MHz and 1 GHz is applied under an atmosphere temperature of 25°C.
