India Centre for Lab Grown Diamond (InCent-LGD) is a research and development centre established by the Indian Institute of Technology Madras (IITM) in collaboration with the Ministry of Commerce and Industry, India.[1][2][3] The centre was established in February 2023 with the aim of developing indigenous technologies for diamond growth and exploring the diverse applications of lab-grown diamonds beyond jewellery, particularly in the field of electronics.[4]
Objectives
- To develop cutting-edge technology for the growth of high-quality lab-grown diamonds.[2][5]
- To explore the semiconducting properties of doped diamonds for applications in high-speed electronic devices and next-generation technologies like 5G/6G communication.
- To investigate the use of diamonds in thermal management systems for improved cooling and heat dissipation.
- To develop diamond-based tools for enhanced machine tool life and performance.
- To explore the potential of diamonds in magnetometry and quantum computing.
Research Groups
InCent-LGD has three core research groups dedicated to different aspects of lab-grown diamond technology:[5]
- High Pressure High Temperature (HPHT) Group: This group focuses on the HPHT method of diamond growth, which simulates the natural diamond formation process by subjecting carbon to high pressure and high temperature.
- Microwave Plasma-enhanced Chemical Vapour Deposition (MPCVD) Group: This group explores the MPCVD method, where a diamond film is grown on a substrate from a carbon-containing gaseous plasma.
- Solid-State Microwave Generators (SSMG) Group: This group develops and optimizes SSMGs, which are crucial components for generating the microwave plasma needed for MPCVD diamond growth.
