Design, Fabrication, and Characterization of Nanoelectronic Devices: From Carbon Nanotubes to Graphene, and Beyond

Fabrication of high-performance electronic devices using novel semiconductors is essential for developing future electronics applications such as large-area, flexible and transparent displays, sensors and solar cells. In the first part of my talk, I will discuss the fabrication of nanoelectronic devices and investigation of their transport properties using carbon nanotubes (CNTs) and graphene as electrode materials.

Multi-messenger Autopsies of Stellar Death

The expanding zoo of astronomical transients has become one of the most important driving forces of scientific discovery in extreme astrophysics. Increasingly sophisticated all-sky surveys are uncovering unexpected phenomena that are forcing radical revisions to long accepted models of massive star evolution and their compact remnant objects. These discoveries, which will increase by orders of magnitude in the upcoming decade, are shaping the priorities of the next generation of science facilities such as the Large Synoptic Survey Telescope and Extremely Large Telescopes.

There is no scheduled Physics Colloquium for Friday, October 18 2019.

Tuning Magnetic Anisotropy in Nanostructures for Biomedical Applications

Magnetic nanoparticles have been building blocks in applications ranging from high density recording to spintronics and nanomedicine. Magnetic anisotropies in nanoparticles arising from surfaces, shapes and interfaces in hybrid structures are important in determining the functional response in various applications. In this talk, I will first introduce the basic aspects of anisotropy, how to tune it in nanostructures and ways to measure it. I will discuss resonant RF transverse susceptibility, that we have used extensively, as a powerful method to probe the effective anisotropy in magnetic materials.

Quantum Universe

Observations show the cosmos to be astonishingly simple, and yet deeply puzzling, on the largest accessible scales. How did everything we see emerge from a singular “point” in the past? Why is there a cosmological constant (or dark energy) and what fixes its value? What caused the density variations which seeded the formation of galaxies? All these questions involve the interplay between quantum mechanics and spacetime.
