This study is divided into three parts. The first part is to grow silicon-doped graphene by chemical vapor deposition using polydimethylsilane precursor by the heating belt melted. Graphene films were analyzed by Raman spectroscopy, UV-vis spectroscopy, and X-ray phototeletron spectroscopy. In the Raman spectrum, it can be found that there are differences between pure graphene (PG) and Si-doped graphene (SiG). The D band intensity for SiG is higher than for PG and the G band for SiG has a G' branch side. These differences in Raman spectra can be attributed to defects in lattice-deformed graphene. The second part focuses on the response of graphene Schottky device to ammonia gas. PG and SiG are applied to PG/n-Si and SiG/n-Si Schottky diodes and placed in a self-made vacuum chamber to dilute ammonia gas to measure their gas sensing effect. The I-V curves were measured under dark in a vacuum chamber at room temperature. The Schottky barrier height of the PG/n-Si and SiG/n-Si Schottky device were calculated by the thermionic emission theory were 0.735 eV and 0.750 eV, respectively. The Schottky devices were further placed into ammonia gas environment with different concentrations for dynamic and static analysis. The Schottky barrier height of the two devices increased slightly when the NH3 gas was changed from high to low concentrations. PG/n-Si Schottky device has a response of about 7.3% at a high concentration of 500 ppm and a response of about 1.5% at a low concentration of 5 ppm in dynamic response measurement; SiG/n-Si Schottky device has a responsivity of approximately 11% at a high concentration of 500 ppm and a responsivity of approximately 2% at a low concentration. For quantitative dynamic cycle analysis with NH3 of 5 ppm to 10 ppm, the response time and recovery time were observed to be 238 s and 229 s, and the response was 5.4% for the SiG/n-Si. The response for PG/n-Si is around 3.4%. Consequently, SiG/n-Si device has a good response to NH3 then the PG/n-Si. For the third part, we analyze sensor response under UV and IR ligh. From the experimental results, the light irradiation hinders the adsorption of ammonia gas to the device, resulting in a large decrease in the responsiveness of the component and an increase in the response time.

In this thesis, we utilize the special electrical properties and high surface of graphene for the gas sensing application. Graphene prepared by chemical vapor deposition(CVD) was transferred on the patterned silicon substrate in order to form Schottky barrier diode. The thermionic theory was implemented to discuss the gas sensing mechanism. It is found that the work function of graphene is changed when the molecules of target gas were adsorbed on graphene surface. This behavior changes the Schottky barrier height between the interface of graphene and silicon as well as the electric properties of the device. Accordingly, the magnitude of the current reveals the concentration of target gas. Furthermore, to enhance the adsorption ability of graphene, its surface is decorated by gold or platinum. It is found that the fabricated devices can serve as a highly sensitive gas sensor because the noble metals decorated on graphene surface can enhance the interaction between graphene and gas molecules. This research is therefore helpful for the application of graphene in biosensors and gas sensors.

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.

Developing better contacts on Si is one of the main challenges for Si-based device technology. The present work reports the fabrication and detailed electrical properties of graphene/n-type Si Schottky diodes. The graphene/n-type Si Schottky diodes were treated by annealing. The current–voltage characteristics in the temperature range of -120 oC ~ 30 oC were analyzed on the basis of thermionic emission theory. Through the analysis, it can be suspected that a SiOX layer at the graphene/n-type Si interfaces influences the electronic conduction through the device and stoichiometry of SiOX is affected by annealing treatment. It is found that both Schottky barrier inhomogeneity and the T0 effect are affected by annealing treatment, implying that stoichiometry of SiOX has a noticeable effect on the inhomogeneous barriers of graphene/n-type Si Schottky diodes. In addition, some of the n-type Si samples were dipped in the H2O2 solution at 60 oC for 10 min (referred to as H2O2-treated n-type Si samples). The graphene/n-type Si Schottky diode without H2O2 treatment shows a poor rectifying behavior with an ideality factor (η) of 3.5 and high leakage. However, the graphene/H2O2-treated n-type Si Schottky diode shows a good rectifying behavior with η of 1.9 and low leakage. We believe the inhomogeneous Schottky barrier height has a relation to interface states; and, such result can be attributed to a nonstoichiometric SiOX layer at the graphene/n-type Si interface.
