Welcome to the web page of Nano Scale Surface Science Research Laboratory of Istanbul Technical University; Faculty of Sciences and Letters, Physics Department.
Since the beginning of our efforts to build our laboratory, by the end of year 2008; we have been focusing on the study of morphological and electronic structure of surfaces and interfaces by means of scanning probe microscopy, and various other surface related techniques; with a focus on Scanning Tunneling Microscopy (STM). We are not only interested in the study of physical systems but we also run projects on the development of scanning probe microscopy techniques for our area of interest.
Currently we are occupied with various projects: Our studies involve the study of moire patterns at the atomic scale on surfaces as well as the investigation of electronic and morphological structure of graphene/surface systems at the atomic level. We investigate the properties of colloidal quantum dots on HOPG and gold surfaces and at the same time we are interested in the formation processes and the structure of nano scale oxides at surfaces. With the help of a home made ambient chemical vapor deposition system we produce graphene and multi layer graphene crystals on metal foils and we investigate the structures that form as a function of the growth parameters. In a different project we study the surface structure of various materials those are relevant for organic electronics applications. Recently we have started the investigation of electronic and structural properties of various topological insulators such as Bi2Te3, at the atomic level. Moreover we are running a collaborative effort on understanding the physical properties of graphitic surfaces those are bombarded with swift heavy ions. Certainly we not only produce or acquire interesting nano scale structures at surfaces and investigate them, but also we develop the techniques those are required to investigate them. In one of our projects we developed a system by means of which we can collect the photons emitted from the tunnel junction of an STM system. With the help of this photon-STM set up we study the plasmonic properties of surfaces at the nano scale.
Among these pages you can find information on our studies as well as our running and competed projects. You can take a brief look at our facilities and see who takes part in our research efforts and learn about who the NanoBEEs are, both current and alumni.
Our laboratories are located at the Physics Department of the Faculty of Sciences and Letters of Istanbul Technical University, Maslak Campus. You can contact us any time by means of our contact information or you can visit us whenever you like. If you want to join our research, please feel free to contact.
