Abstract

This paper presents synthesized diamond films by using combustion activated chemical vapor deposition (CACVD) techniques. The characteristics of diamond films have been studied at wide ranges of temperature (30-400°C). The resistance of diamond films has been determined for hydrogen termination times of 5, 10, 15, and 20 minutes, and at the operation temperatures of 500, 600, and 700°C. The investigation found that, at 30°C a synthesized diamond film has a high resistance (1010 ), whereas at high temperatures (100-400°C) the resistance has decreased from 4.04 M to 2.42 M. The result obtained from the hydrogen termination showed that the resistance has decreased by 105-106  (at 30°C). Summarily, it can be stated that the higher the hydrogen termination times and operation temperatures, the lower the resistance of diamond films.
