Researchers find a new way of building voltage controlled quantum circuits using a combination of graphene and alpha molybdenum trioxide.

Prof Bhaskaran Muralidharan and Dr Alestin Mawrie of the Indian Institute of Technology Bombay have researched a specific category of two-dimensional nanomaterials, called semi-Dirac materials. Their theoretical studies show that it is possible to engineer semi-Dirac materials to make optical filters and efficient thermoelectric nanodevices.

Researchers find a unique new technique to make stable, low-power graphene transistors

Graphene, a sheet-like form of carbon, has been hailed as a wonder material owing to its many promising applications in electronics, drug delivery and more. In a recent study, a team of scientists from India and the USA, led by Prof Srinivasan Raghavan and Prof Rudra Pratap from the Indian Institute of Science (IISc), Bengaluru, has paved the way for new applications of graphene by intentionally varying the defects formed during its production.

Researchers at Raman Research Institute, Bengaluru, are exploring the properties of single walled carbon nanotube (CNT) immersed in aqueous triblock copolymer solution. The newly formed CNT-polymer hybrid could replace the use of carbon nanotubes by itself, thanks to its remarkable mechanical, thermal and electrical properties.

Graphene is called the ‘wonder material’ due to its electrical and mechanical properties and is now evolving as an alternative to conventional energy storage devices like batteries and supercapacitors. Researchers from Institute of Nano Science and Technology (INST), Mohali, use peanut shells to manufacture high-quality graphene nanosheets.

Graphene is a form of carbon, just like diamond and graphite. It is made of a honeycomb shaped sheet of single layer of carbon atoms. Researchers from the Indian Institute of Science and University of Alabama have studied this material for its property of conducting electricity. Their study indicates that electrons can flow easily on the edges of graphene making it a very good conductor of electricity. 

Graphene, also called a “wonder material” is increasingly being used in the field of electronics due to its lightweight and electrical properties. Now, researchers at the Indian Institute of Science, Bangalore, have identified a potential drawback in graphene transistors that have metal contact leads. The metal atoms in the contacts react with graphene atoms, creating an unwanted disturbance or noise in the electronic circuit. This discovery may have major implications on using graphene for futuristic electronic applications.
