PURPOSE:To synthesize diamond thin film in a solution at a low temperature by heating an organic solution, impressing negative high voltage to a base and defining electric current density of the base. CONSTITUTION:An organic solution 1 is heated by a heater 3 (controlled using a thermocouple 6) and negative high voltage (e.g. several 100V) is impressed to a base 2 (e.g. silicon base) (by electric power source 5 and a positive electrode 4) and simultaneously electric current of the order of mA/cm<2> is turned on to synthesize diamond thin film from a solution. For instance, ethanol, acetone, benzene, trichloroethylene or methyl acetate, etc., is exemplified as the organic solution and especially electroconductive property of a diamond film made from ethanol is excellent. |
