  1. IWCN 2021: How to Preserve the Kramers-Kronig Relation in Inelastic Atomistic Quantum Transport Calculations

    15 Jul 2021 | | Contributor(s):: Daniel Alberto Lemus, James Charles, Tillmann Christoph Kubis

    The nonequilibrium Green’s function method (NEGF) is often used to predict quantum transport in atomically resolved nanodevices. This yields a high numerical load when inelastic scattering is included. Atomistic NEGF had been regularly applied on nanodevices, such as nanotransistors....

  2. IWCN 2021: Interfacial Trap Effects in InAs Gate-all-around Nanowire Tunnel Field- Effect Transistors: First-Principles-Based Approach

    15 Jul 2021 | | Contributor(s):: Hyeongu Lee, SeongHyeok Jeon, Cho Yucheol, Mincheol Shin

    In this work, we investigated the effects of the traps, Arsenic dangling bond (AsDB) and Arsenic anti-site (AsIn) traps, in InAs gate-all-around nanowire TFETs, using the trap Hamiltonian obtained from the first-principles calculations. The transport properties were treated by nonequilibrium...

  3. IWCN 2021: Quantum Transport Simulation on 2D Ferroelectric Tunnel Junctions

    15 Jul 2021 | | Contributor(s):: Eunyeong Yang, Jiwon Chang

    In this work, we consider a simple asymmetric structure of metal-ferroelectric-metal (MFM) FTJs with two different ferroelectric materials, Hf0.5Zr0.5O2(HZO) and CuInP2S6(CIPS), respectively. To investigate the performance of FTJs theoretically, we first explore complex band structures of HZO...

    15 Jul 2021 | | Contributor(s):: raseong kim, Uygar Avci, Ian Alexander Young

    In this preentation, we review our journey of doing CMOS channel material benchmarking for future technology nodes. Through the comprehensive computational research for past several years, we have successfully projected the performance of various novel material CMOS based on rigorous physics...

  5. IWCN 2021: Ab initio Quantum Transport Simulation of Lateral Heterostructures Based on 2D Materials: Assessment of the Coupling Hamiltonians

    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...
