Title:
BISMUTH-DOPED SEMI-INSULATING GROUP III NITRIDE WATER, AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2019011245
Kind Code:
A
Abstract:
To provide a bismuth-doped semi-insulating group III nitride wafer, and a method for producing the wafer.SOLUTION: The present invention discloses a bismuth-doped (Bi) semi-insulating wafer of GaAlInN(0≤x≤1, 0≤x+y≤1). The semi-insulating wafer has the resistivity of 10ohm/cm or more. Although it is extremely difficult to obtain a single crystal ingot of group III nitride wafer, an ammonothermal method is capable of growing high-orientation polycrystal or single crystal ingot of group III nitride which has less than 10cmof dislocation/grain boundary density. The present invention also discloses a method for processing a semi-insulating group III nitride bulk crystal and wafer.SELECTED DRAWING: Figure 1
