Özet

Although quite a few number of theoretical and experimental studies are still carried out on metal-semiconductor contacts which forms in case of a tight contact of metal and semiconductor under high temperature and vacuum, the formation and transmission mechanisms of the barrier between metal and semiconductor have not yet been fully elucidated. Since the initial detailed studies about these structures were made by W. Schottky, these metal-semiconductor contacts are generally known as Schottky diodes/structures. It has been tried to improve the performance of the Schottky structures without or with interfacial layers such as insulator or polymer and ferroelectric by using various materials with different physical, chemical and electrical properties from past to present. The significant features not found in other diodes, such as its ability to operate at very high frequencies and low forward bias, and very fast switching capability, the widespread use in electronic technology, and the fact that its technology is open for development encourage scientists to study on Schottky structures. Together with the investigation of the metal-semiconductor and the metal-semiconductor with interfacial layer Schottky structures by considering the scientific studies on Schottky structures, the observation of its progress over time, the statistical analysis of academic studies in this area over the world and Turkey have been made in this study. Ultimately, it is aimed to reveal the situation of Turkey over the world in terms of scientific studies. At the same time, to what extent the scientific studies on distinct MS structures get reciprocity in the world and in Turkey is set forth. The analysis of the academic studies which are scanned by Science Citation Index (SCI) in Web of Science database and made in Turkey as well as all over the world were performed with data mining by utilizing automated data collection methods and SQL Server Management Studio program. The statistical analysis results indicate that the academic studies made for every type of Schottky structures over the world and Turkey increase for almost every year
