Abstract: 

Emergent physical properties of low-dimensional nanostructures have served as major drivers of research in nanoelectronics and nanophotonics science and engineering for many years. These attributes have been often utilized to implement faster, more energy-efficient, and more complex (opto)electronic devices for a wide range of applications including optical communications, classical/quantum computing, sensing/imaging, and energy harvesting from renewable resources.

 

This seminar will discuss device application of several classes of novel nanostructures including graphene and graphene-like materials, nano-plasmonic structures, and metamaterials. We will discuss that highly localized interaction of electromagnetic radiation with the electronic structure of these nano-devices, particularly in 2D quantum materials like graphene, offer new avenues to access quantum coherence at the mesoscopic scale. In this new class of nanodevices, quantum-coherent correlations among electrons offer a variety of novel electronic, optical, magnetic, and chemical phenomena.

 

In this talk, I will elaborate on some of the fundamental physical properties of these structures, highlight several important device applications, and discuss my research with regards to their design, fabrication, and characterization. This will include nanophotonic devices for optoelectronic and sensing applications as well as nanoelectronic devices for information processing and metrology.
