  3. The Role of Interfaces and Defects on the Thermal Transport in Nano-Electronic Semiconducting Materials

    14 Jan 2020 | Contributor(s):: Yan, Zhequan

    Advisors: Satish Kumar, Zhuomin Zhang, Eric Vogel, Seung Soon Jang, Matthew McDowellAs the device dimension scales down and power dissipation increases in the electronic devices, the inefficient thermal management becomes challenging for the performance and reliability. Phonons are expected to be...

  4. Computational Characterization of Disordered Metal-Organic Frameworks

    29 May 2019 | Contributor(s):: Han, Rebecca

    Advisors: David S Sholl, Ryan P Lively, Krista S Walton, Angus P Wilkinson, Sankar NairMetal-organic frameworks (MOFs) are a class of crystalline nanoporous adsorbents with numerous applications due to their highly tunable physical and chemical properties. However, MOFs are limited by their...

  5. Computational Study of Point Defects in Metal-Organic Frameworks

    16 Jan 2019 | Contributor(s):: Han, Chu

    Advisors: David S. Sholl, Angus P. Wilkinson, Thomas M. Orlando, Meilin Liu, David SherrillMetal-Organic Frameworks (MOFs) are a class of porous materials composed of metal clusters connecting by organic ligands and forming in one-, two-, or three- dimensional structures. The tunable pore sizes,...

  6. Investigation Into Obstacles to the Implementation of the Directed-Self Assembly of Block Copolymers

    31 May 2018 | Contributor(s):: Breaux, Caleb Lamar

    Advisors: Clifford L. Henderson, Peter J. Ludovice, Carson J. Meredith, Zhiqun Lin, David BucknallTo meet the growing demands of the microelectronics industry and their desire to continue Moore's Law, a variety of routes to extend or replace optical lithography have beensuggested. Among these...
