and Topological Materials

2 0 2 4

Welcome to our workshop page! 😃

The e-ASIA Workshop on Thermoelectrics of Low-Dimensional and Topological Materials 2024 was successfully held on August 6-7, 2024 (Tue-Wed).

💡 Introduction

Thermoelectricity exploits the ability of materials to convert heat directly into electrical energy. Materials with unique electronic structures and quantum properties are promising for advancing thermoelectric performance. Low-dimensional materials such as various nanostructures and two-dimensional layered materials offer tailored band structures and reduced thermal conductivity, while topological materials exhibit robust surface states and protected fermions, facilitating efficient charge and heat transport mechanisms.

Throughout this workshop, we will explore the fundamental principles governing thermoelectric phenomena in low-dimensional and topological materials. Some keynote presentations will elucidate the frameworks underpinning thermoelectric performance metrics, complemented by hands-on sessions featuring computational tools like Quantum ESPRESSO, BoltzTraP2, and OpenMX. These tools enable participants to investigate electronic band structures, phonon dynamics, and transport properties essential for optimizing thermoelectric efficiency at the nanoscale.

Additionally, experimental studies will showcase advancements in material synthesis, characterization techniques, and device fabrication. By fostering interdisciplinary collaborations and a data-driven approach among researchers with various backgrounds, this workshop aims to push innovations in sustainable energy solutions with the thermoelectric platform. Together, we aim to harness the distinct properties of low-dimensional and topological materials to convert waste heat into valuable electrical power, paving the way toward a greener and more efficient future.

This workshop is organized by members of the “2DTopoMatTE” e-ASIA joint research program, involving some professors and researchers from (1) Kanazawa University, Japan, (2) Sakon Nakhon Rajabhat National University, Thailand, (3) Institut Teknologi Sepuluh Nopember, Indonesia, (4) Institut Teknologi Bandung, Indonesia, and (5) National Research and Innovation Agency (BRIN), Indonesia. The BRIN Research Center for Quantum Physics has been appointed to host this year’s event.
