Dynamical Spin Injection In Graphene, Simranjeet Singh Jan 2014

Dynamical Spin Injection In Graphene, Simranjeet Singh

Electronic Theses and Dissertations

Within the exciting current trend to explore novel low-dimensional systems, the possibility to inject pure spin currents in graphene and other two-dimensional crystals has attracted considerable attention in the past few years. The theoretical prediction of large spin relaxation times and experimentally observed mesoscopic-scale spin diffusion lengths places graphene as a promising base system for future spintronics devices. This is due to the unique characteristics intrinsic to the two-dimensional lattice of carbon atoms forming graphene, such as the lack of nuclear spins and weak spin-orbit coupling of the charge carriers. Interestingly for some spintronic applications, the latter can be chemically ...


Electronic Properties And Atomic Scale Microscopy Of Two Dimensional Materials: Graphene And Molybdenum Disulfide, Jyoti Katoch Jan 2014

Electronic Properties And Atomic Scale Microscopy Of Two Dimensional Materials: Graphene And Molybdenum Disulfide, Jyoti Katoch

Electronic Theses and Dissertations

Novel two dimensional nanoscale materials like graphene and metal dichalcogenides (MX2) have attracted the attention of the scientific community, due to their rich physics and wide range of potential applications. It has been shown that novel graphene based transparent conductors and radiofrequency transistors are competitive with the existing technologies. Graphene’s properties are influenced sensitively by adsorbates and substrates. As such not surprisingly, physical properties of graphene are found to have a large variability, which cannot be controlled at the synthesis level, reducing the utility of graphene. As a part of my doctorate dissertation, I have developed atomic hydrogen as ...
