Growth of Ni and Ni-Cr Alloy Thin Films on MgO(001): Effect of Alloy Composition on Surface Morphology
Gopalakrishnan Ramalingam, Petra Reinke
The effects of substrate treatment, temperature and composition on the surface morphology of Ni-Cr thin films grown on MgO(001) are studied by scanning tunneling microscopy (STM) a…
3D Nanostructures on Ge/Si(100) Wetting Layers: Hillocks and Pre-Quantum Dots
Gopalakrishnan Ramalingam, Jerrold A. Floro, Petra Reinke
The annealing of sub-critical Ge wetting layers (WL<3.5 ML) initiates the formation of 3D nanostructures, whose shape and orientation is determined by the WL thickness and thus dir…
A nearly relaxation-free opto-electronic memory from ultra-thin graphene-MoS binary hybrids
Kallol Roy, Medini Padmanabhan, Srijit Goswami +4
Ultra-thin planar heterostructures of graphene and other two-dimensional crystals have recently attracted much interest. Very high carrier mobility in a graphene-on-boron nitride a…
Electrochemical integration of graphene with light absorbing copper-based thin films
Medini Padmanabhan, Kallol Roy, Gopalakrishnan Ramalingam +2
We present an electrochemical route for the integration of graphene with light sensitive copper-based alloys used in optoelectronic applications. Graphene grown using chemical vapo…
