    Research Highlight: Jagadeesh S. Moodera
    Laying a foundation for quantum electronics 

    MIT Senior Research Scientist Dr. Jagadeesh S. Moodera stands in front of a custom-built cluster molecular beam epitaxy _MBE_ system used to fabricate ultra thin films. He studies  devices that exhibit resistance-free_ spin-polarized current.

    A pioneer in the field of spin-polarized magnetic tunnel junctions, which led to a thousand-fold increase in hard disk storage capacity, MIT Physics Department Senior Research Scientist Dr. Jagadeesh S. Moodera is using his expertise working with atomically thin materials to lay a step-by-step foundation for a new generation of quantum computers.
     
    Moodera's group is making progress toward devices that display resistance-free, spin-polarized electrical current; memory storage at the level of single molecules; and capturing the elusive paired electron "halves" known as Majorana fermions, which are sought after as qubits for quantum computing.

    Laptop computer users operating their devices on their laps will be familiar with the heat they generate which is caused by electrical resistance that converts waste energy to heat. Scientists dream of creating electronic devices with little or no resistance to the flow of electricity, in order to reduce heat output, save energy, and extend device capabilities. 
     
    MIT Postdoctoral Associate Cui-Zu Chang and colleagues in the group of Dr. Jagadeesh Moodera, along with collaborators from Penn State, Stanford and Northeastern Universities, achieved near dissipationless electron transport in a topological insulator system that draws its inherent magnetism from vanadium.

    A new spin on circuits 
    Researchers create edge currents in graphene, superconductivity in gold, in march toward quantum devices.

    Postdoctoral Associates Peng Wei, Ferhat Katmis and Cui-Zu Chang are exploring electron "spin" in materials just a few atoms thick to create electronic systems that eliminate heating problems and distance limits.
     
    The researchers showed that layered, thin films of europium sulfide and graphene produces novel ground states in graphene that carry spin-polarized edge currents, which are potentially useful for spin-based memory and computing devices. At their interface, graphene can "feel" the huge internal exchange field or "quantum magnetic field" from the europium sulfide, Wei explains.   Read more

    About MPC

    The goals of the Materials Processing Center are to unite the materials research community at MIT and to enhance Institute-industry interactions. Collaboration on research ventures, technology transfer, continuing education of industry personnel, and communication among industrial and governmental entities are our priorities. The MPC 
    Industry Collegium is a major vehicle for this collaboration. The MPC sponsors seminars and workshops, as well as a summer internship for talented undergraduates from universities across the U.S. We encourage interdisciplinary research collaborations and provide funds management assistance to faculty.
