Research at Saroj Dash group is currently focused on spin and quantum transport in atomically thin 2D quantum materials-based devices for nanoelectronics, spintronics, topological quantum electronics, and neuromorphic computing applications.
Our group investigates atomically thin two-dimensional (2D) quantum materials and their hybrid devices for electronic, spintronics, and quantum technologies and neuromorphic computing applications. We fabricate nanoelectronic devices with 2D materials such as graphene, semiconductors, magnets, superconductors, topological quantum materials, and their heterostructure to discover new physics and realize new device concepts.
We aim to discover unique properties of these low dimensional materials and heterostructures by tailoring their crystal and time reversal symmetries, band structure design, tuning Berry curvature and quantum metrics, spin-orbit interactions, proximity induced effects, and tunability by twist angle control of 2D materials.
The use of modern state-of-the-art nanoscale device fabrication techniques and the development of new methods of materials growth, heterostructure preparation, and characterization of nanoscale devices with a range of frequencies, cryogenic temperatures, and high magnetic fields are essential parts of our research.

Breakthrough in magnetic quantum material paves way for ultra-fast sustainable computers
The discovery of new quantum materials with magnetic properties are believed to pave the way for ultra-fast and considerably more energy efficient computers and mobile devices. So far, these types of materials have been shown to work only in extremely cold temperatures. Now, a research team at Chalmers University of Technology in Sweden are the first to make a device made of a two-dimensional magnetic material work in at room temperature.
Pioneering research on nanoelectronics with 2D quantum materials awarded
Saroj Dash, Professor at Quantum Device Physics, is awarded the Wallmarkska Prize 2023 by the Royal Swedish Academy of Sciences for his "groundbreaking research on spintronics in new 2D layered materials, not least graphene, as well as topological and magnetic layers." The research is now expected to play an important role in the development of the next generation of computers.
Anamul Hoque and Agin Vyas awarded PhD prizes
"This recognition will embolden me to continue with my research endeavors and support society through my research," says Md Anamul Hoque, who along with Md Agin Vyas received this year's PhD prizes from VINNOVA Competence Centre 2D-TECH and Graphene Centre at Chalmers earlier this week.
The spin in graphene can be switched off
By combining graphene with another two-dimensional material, researchers at Chalmers University of Technology have created a prototype of a transistor-like device for future computers, based on what is known as spintronics. Spin as the information carrier can result in electronics that are significantly faster and more energy efficient. It can also lead to more versatile components capable of both data calculation and storage. The discovery is published in the scientific journal Nature Communications.
Spin current on topological insulator detected electrically at room temperature
Researchers at Chalmers University of Technology have for the first time reported the electrical detection of spin current on topological insulator surfaces at room temperature by employing a ferromagnetic detector. The findings have been published in the journal Nano Letters.
