A Machine Learning Aided Hierarchical Screening Strategy for Materials Discovery
09 Sep 2021   Contributor(s):: Anjana Talapatra
In this tutorial, we illustrate this approach using the example of wide band gap oxide perovskites. We will sequentially search a very large domain space of single and double oxide perovskites to identify candidates that are likely to be formable, thermodynamically stable, exhibit insulator...

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 metalferroelectricmetal (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...

IWCN 2021: Density Functional Theory Modeling of Chemical Reactions at Interfaces
15 Jul 2021   Contributor(s):: Namita Narendra, Jessica Wang, James Charles, Tillmann Christoph Kubis
In this work, we introduce a DFTbased method to predict energies of solute molecules in bulk solution and in various distances to solvent/air interfaces. The solute and all solvent molecules (~1400 atoms) are explicitly considered, and their electrons solved selfconsistently in density...

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 latticematched 2D materials are a promising option to design efficient electron devices such as MOSFETs [1], tunnelFETs [2] and energyfiltering FETs [3]. In order to rigorously describe the transport through such heterostructures, an abinitio approach based...

IWCN 2021: Thermoelectric Properties of Complex Band and Nanostructured Materials
14 Jul 2021   Contributor(s):: Neophytos Neophytou, Patrizio Graziosi, Vassilios Vargiamidis
In this work, we describe a computational framework to compute the electronic and thermoelectric transport in materials with multiband electronic structures of an arbitrary shape by coupling density function theory (DFT) bandstructures to the Boltzmann Transport Equation (BTE).

Active Learning via Bayesian Optimization for Materials Discovery
25 Jun 2021   Contributor(s):: Hieu Doan, Garvit Agarwal
In this tutorial, we will demonstrate the use of active learning via Bayesian optimization (BO) to identify ideal molecular candidates for an energy storage application.
