Patent ID: 7364714

Claim:
A synthesizing method of 3C—SiC nanowhiskers, characterized in that it comprises the steps of: predetermining a desired diameter of the 3C—SiC nanowhisker; selecting a thickness of a thin film made of a metal element or metal elements based on the predetermined desired diameter of the 3C—SiC nanowhisker; depositing said thin film on a Si substrate to said selected thickness; and holding said Si substrate in a plasma consisting of hydrogen and hydrocarbon for a time period at a substrate temperature, wherein said thin film having said selected thickness becomes a liquid phase to form metal liquid fine particles having a diameter proportional to said thickness of said thin film on said Si substrate, nuclei for said 3C—SiC nanowhiskers are formed on the surface of said metal liquid fine particles by Si atoms of said Si substrate and C atoms from said hydrocarbon decomposed in said plasma dissolving into said metal liquid fine particles, and then said 3C—SiC nanowhiskers having said predetermined desired diameter grow from said Si atoms and C atoms continuously being supplied to said nuclei, wherein a root of said 3C—SiC nanowhisker is buried in said Si substrate by supplying Si of said 3C—SiC nanowhisker from said Si substrate, and fixed with said Si substrate by said metal liquid fine particle existing at said root forming a silicide with said Si substrate and said 3C—SiC nanowhisker is grown perpendicular to said Si substrate.
