Srinivasan Raghavan

Srinivasan Raghavan

Expertise: GaN epitaxy on Si, sapphire, and SiC by MOCVD; stresses and defects during epitaxial growth; growth-device performance correlation

Background: Professor Srinivasan Raghavan, or Vasu, is a material scientist by training and the current Chair of the Centre for Nano Science and Engineering (CeNSE), IISc. He joined IISc in 2006 and has focused his research on the interface of materials engineering and device technology. Vasu was a key member of the team responsible for building the nanofabrication and characterization facility at CeNSE, India’s largest fab in an academic setting. Since its establishment, the CeNSE fab has provided a huge boost to Indian RnD efforts in the semiconductor science and technology space and continues to do so. Vasu has also led the team involved in setting up and running a consistent GaN materials and device development platform at CeNSE. These activities culminated in the submission of a proposal to the Government of India to set up India’s first GaN fab and ecosystem enabler, GEECI, with Vasu as the Project Coordinator.
