| Summary: | 碩士 === 東海大學 === 電機工程學系 === 106 === In this research, soybean oil and wasted engine oil are made into graphene-like materials by high-temperature rapid annealing system, and nickel and nickel films are used as catalysts. Moreover, this research uses different oil quantities as carbon sources. The samples with semiconductor behavior in the above conditions are made into the research of the Schottky diode.
In the first research, different amount of used engine oil are heated at 800 degree C in a high temperature rapid thermal annealing system, with a nickel plate. Some region of samples in 0.1g and 0.2g oil are found to have the semiconductor behavior and the characteristics of the graphite-like.
In the second research, different amount of soybean oil are heated at 800 degree C in a high temperature rapid thermal annealing system, with a nickel plate. It was found that the components in the used oil will affect the characteristics of the sample.
The third study used different oils of soybean oil and waste engine oil in a high-temperature rapid annealing system for 800 ° C heating in the atmosphere. With nickel film, we found that samples with a sample of 0.05g oil have semiconductor and graphite-like behaviors.
The fourth research is to use sputtering metal method on the semiconductor behavior samples under above conditions to make MS diode for measurement. Some samples have good IV and CV curves. However, a few samples are presumed to be broken when graphene-like is stripped from the nickel sheet by tape. As the result, the characteristics of these MS diode are not observed.
