Abstract:
1. A low pressure and low temperature process for growing gallium nitride whiskers from solution, comprising: (a) charging a reaction vessel with a gallium composition comprising gallium mixed with at least one of bismuth and antimony, a Group IA element material, and gallium nitride; (b) placing the charged reaction and vessel into a chamber; (c) applying a nitrogen gas pressure of 0.1 to 20 MPa to the reaction vessel; (d) applying a temperature of between 700 to 900° C. to the reaction vessel (i) to cause the gallium nitride from the gallium nitride and/or nitrogen to dissolve in the solvent comprising gallium, at least one of bismuth and antimony, and the Group IA element; (ii) to form a solution; and (iii) to precipitate gallium nitride out of the solution exclusively in the form of gallium nitride whiskers.
