  1. DRC202 Device Research Conference Technical Presentations

    14 Oct 2020 | | Contributor(s):: Siddharth Rajan (editor), Zhihong Chen (editor), Becky (R. L.) Peterson

    For over seven decades, the Device Research Conference (DRC) has brought together leading scientists, researchers and students to share their latest discoveries in device science, technology and modeling. Notably, many of the first public disclosures of key device technologies were made at the...

  2. A3 Crystalline Calcium Fluoride: A Record-Thin Insulator for Nanoscale 2D Electronics

    18 Sep 2020 | | Contributor(s):: Yury Yuryevich Illarionov, A.G. Banshchikov, Theresia Knobloch, D.K. Polyushkin, S. Wachter, V.V. Fedorov, M. Stöger-Pollach, M.I. Vexler, N.S. Sokolov, T. Grasser

    We fabricated high-quality crystalline 1−2nm CaF2 films and successfully used them for MoS2 FETs with record-thin gate insulators. For the first time we demonstrated MoS2 FETs with simultaneously sub-1nm EOT insulators and sub-100nm channel length and found that these devices can exhibit...

  4. 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.

  5. 2D Valley-Spin Transport in Transition Metal Dichalcogenides

    07 May 2020 | | Contributor(s):: Zhihong Chen

    In this talk, we first report that valley current can be electrically induced and detected through the valley Hall effect and inverse valley Hall effect, respectively, in monolayer molybdenum disulfide. We compare temperature and channel length dependence of non-local electrical signals in...

  6. 3 min. Research Talk: Identifying the Dimensionality of Crystal Structures

    12 Feb 2020 | | Contributor(s):: Franco Vera

    Today, researchers worldwide have identified over 100,000 distinct bulk materials. The underlying dimensionality of these materials is not always clear however, and as such researchers have sought to identify stable, lower dimensional materials derived from the bulk parent structures. A team of...

  7. Identifying Dimensionality of Periodic Crystals

    Query submit and analyse graphene sythesis data.

  9. 2D material reflectance spectra

    10 Jul 2019 | | Contributor(s):: Vu Dang Nguyen, Yunsu Park, Darren K Adams (editor), Hayden Taylor

    Simulation of the reflectance spectra of 2D materials and image analysis for thickness identification

  10. Energy Transport in Bi-Te-Se Topological Insulators

    21 Mar 2019 | | Contributor(s):: Shouyuan Huang, Vasudevan Iyer, Xianfan Xu

    Topological insulators (TIs) are a new phase of material that allows metallic conducting electrons at its surface while the bulk is insulating. Besides, the topological surface electrons’ spin orientation is always locked perpendicular to its moving direction, called...

  11. KiriGAMI Design and Analysis Tutorial

    26 Feb 2019 | | Contributor(s):: Subhadeep De

    GAMIAN is a design and mechanical ANalysis tool for KiriGAMI structures. Starting from designing cuts or incisions on any thin-film structure to solving for its final deformed configuration under planar loading, all the steps can be carried out using GAMIAN. GAMIAN provides...
