Abstract:
1. A method for producing an electronic device having a structure of ohmic connection to a carbon element cylindrical structure body, comprising disposing a metal material on a connection objective capable of ohmically contacting a carbon element cylindrical structure body and forming a carbon element cylindrical structure body by chemical vapor deposition using said metal material as the catalyst while accomplishing an ohmic contact between the carbon element cylindrical structure body and the connection objective, wherein the material of said connection objective is Ti, Nb, Si or C, and is alloyed with said metal material by the elevation of temperature during said chemical vapor deposition and a carbon element cylindrical structure body is grown using the particle of said metal material in said alloy as the catalyst for said chemical vapor deposition, and, at the same time, a part of the material of the connection objective is carbidized to join the carbon element cylindrical structural body to the connection objective by ohmic contact.
