Modified Electrical Characteristics of Filtered Cathodic Vacuum Arc Amorphous Carbon Film on n-Si (100) by Heat Treatment

摘要

Carbon allotropes are of great interest recently due to theirs novel applications. This paper examines the electrical behavior of amorphous carbon film, deposited on n-Si substrate by filtered cathodic vacuum are (FCVA) deposition methodology, after treating it at high temperature. XPS data is also used to further understand the material. FCVA amorphous carbon film deposited at 1000V and post deposition heat-treated at 800°C is suggested to achieve a better Ohmic contact to n-Si substrates with total resistance 1200Ω compared to other settings with total resistance up to 2000Ω.
