Research in CENT Group

CENT (Computational & Experimental NanoTechnology) Group led by Dr. Hasan Sahin conducts theoretical and experimental research to identify and understand the fundamental physical mechanisms underlying the surface, interface and transport behavior of crystals and molecular materials. For theoretical investigation of Electronic, Magnetic, Optical, Vibrational and Quantum Transport properties of structures we use state-of-the-art DFT approaches. Team members has a solid expertise on the softwares based on Density Functional Theory. For deeper understanding of experimental results obtained by our collaborators and for experimental realization of our theoretical predictions we also perform collaborative studies with experimentalists.
