Professor Bivas Saha and his team at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bangalore have achieved a significant advancement in materials science by engineering defect-free, single-crystalline metal/compound semiconductor superlattices. This development harnesses interfacial engineering to facilitate thermionic emission, a process where charged particles are emitted from a material due to thermal energy.
These superlattices consist of alternating layers of elemental metals and compound semiconductors, precisely engineered at the atomic scale. The meticulous design of these structures ensures coherent epitaxial growth, resulting in high-quality interfaces that are crucial for efficient thermionic emission. This breakthrough opens new avenues for applications in energy conversion and electronic devices.
The research team includes notable members such as Dheemahi Rao, whose contributions have been instrumental in advancing this field.
This work aligns with JNCASR’s commitment to pioneering research in materials science and nanotechnology, contributing significantly to the development of advanced materials with tailored properties for various technological applications.
