5. Mechanical Exfoliation as a Route to Nanomanufacturing of 2D van der Waals Bonded

   11 May 2020 | | Contributor(s):: Daryl Chrzan

   In this talk I present a mechanical exfoliation method able to reliably produce large patterned monolayer samples and place them with upon a substrate in desired locations. The method relies on the epitaxial strain imposed upon the layer to be exfoliated by the deposition of a thin metallic film.

6. Optoelectronic Spintronics and Quantum Photonics in 2D Materials

   07 Apr 2016 | | Contributor(s):: John Schaibley

   First, I will discuss the physics and applications of 2D heterostructures composed of stacked monolayers of MoSe_2 and WSe_2 . These heterostructures host interlayer valley excitons where the electrons and holes are located in different layers. These spatially indirect excitons exhibit long...

7. Calculation of phonon transmission in Si/PtSi heterostructures

   25 Jan 2016 | | Contributor(s):: Jung Hyun Oh, Mincheol Shin

   In this work we examine the suppression of phonon transport in another example, Si and SiPt heterostructures (3D). This heterostrucure is believed to have the benefit that the electrical conductance can be kept high while the phonon propagation is suppressed due to the large acoustic impedance...

    02 Mar 2010 | | Contributor(s):: Gerhard Klimeck

    Heterostructures such as resonant tunneling diodes, quantum well photodetectors and lasers, and cascade lasers break the symmetry of the crystalline lattice. Such break in lattice symmetry causes a strong interaction of heavy-, light- and split-off hole bands. The bandstructure of holes and the...
