Molecular Spintronics

Electronics and Nanoelectronics devices work based on the modulation of electron transport in the semiconducting materials that has reshaped the modern world. Encoding additional spin degrees of freedom into the conducting electrons has given birth to a new field known as ‘spintronics’. The later has brought a revolution in the field of data storage technology and is the future for quantum computers. The major challenge in the field is to find suitable semiconducting materials that will filter or polarized spins and will retain the spin information intact for a long duration of time during its conduction.

So far the known spintronics materials are based on inorganic semiconducting materials that contain heavy atoms. Generally the heavy atoms have strong spin-orbit couplings (SOC), which limits the retention time of spins in the materials. To get rid of this known fact we will explore several small organic magnetic molecules that have negligible SOC, and find suitable organic molecular spintronics materials.

In this project, we will computationally design and study various organic semiconducting materials and their interfaced properties on different substrates. Apart from designing organic spintronics materials, we will also design single-molecule spin valves that will filter as well as separate spins of nonpolarized current upon external stimuli. In this project the students need to have background in Physics or Physical Chemistry and introductory knowledge of atomic and electronic structures. The basic knowledge of magnetism, quantum mechanics and computers will be a plus.

We are working at the Institute of Nano Science and Technology Mohali, one of the leading research institutes in India in the field of Nano Science. INST is located in Chandigarh, one of the major cities of India.
