Thermal Transport in Layered Materials, Devices, and Systems
Online Presentations | 11 Apr 2024 | Contributor(s):: Eric Pop
The thermal properties of layered materials (like graphene and MoS2) are an active area of investigation, particularly due to their anisotropic and tunable thermal conductivity. We have studied their behavior as part of transistors, where self-heating is a major challenge for performance and...

What Are 2D Materials Good For?
Online Presentations | 11 Apr 2024 | Contributor(s):: Eric Pop
This talk will present my (admittedly biased) perspective of what two-dimensional (2D) materials could be good for. For example, they may be good for applications where their ultrathin nature and lack of dangling bonds give them distinct advantages, such as flexible electronics or DNA-sorting...

DFT with SIESTA, Data Visualization, and a Sophomore-level CURE with the MIT Atomic-Scale Modeling Toolkit
Online Presentations | 09 Apr 2024 | Contributor(s):: David A Strubbe
This presentation will focus on use of the density-functional theory (DFT) code SIESTA and visualization code XCrySDen, for calculations of structure, density, and wavefunctions, and visualization of these quantities as well as of Brillouin zones and Fermi surfaces. He uses the toolkit for a...

Hydrodynamic Phenomena in Thermal Transport
Online Presentations | 01 Sep 2022 | Contributor(s):: F. Xavier Alvarez
The talk will cover some of the most recent evidences in the theoretical and experimental research on thermal transport and we will analyze them in the framework of the Kinetic/Collective model (KCM), developed to give a more generalized framework to describe thermal experiments.

Novel Two-dimensional (2D) Materials and Devices for Biomimetic Sensing and Computing
Online Presentations | 16 Aug 2021 | Contributor(s):: Saptarshi Das, NACK Network
Many animals outsmart humans in sensory skills. In fact, animals can do much more than just see, smell, touch, taste, and hear. For example, octopuses possess polarized vision, bats use ultrasound to echolocate, hyper touch sensitive spiders can trace the origin of micro-vibrations and sharks can...

IWCN 2021: Ab initio Quantum Transport Simulation of Lateral Heterostructures Based on 2D Materials: Assessment of the Coupling Hamiltonians
Online Presentations | 14 Jul 2021 | Contributor(s):: Adel Mfoukh, Marco Pala
Lateral heterostructures based on lattice-matched 2D materials are a promising option to design efficient electron devices such as MOSFETs [1], tunnel-FETs [2] and energy-filtering FETs [3]. In order to rigorously describe the transport through such heterostructures, an ab-initio approach based...

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

Mechanical Exfoliation as a Route to Nanomanufacturing of 2D van der Waals Bonded
Online Presentations | 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.

2D Valley-Spin Transport in Transition Metal Dichalcogenides
Online Presentations | 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...
