the patent cover a new method of using benssel beam femtosecond laser to produce ultra thin TMDCs sheets quickly and cheaply. Its novel and incentive because the laser precisely breaks weak interlayer forces.
Patent is an intellectual property right granted by the government to the inventor. Its purpose is to prevent from selling, making, using or importing an invention without the permission of the inventor, the period is of 20 years from the filing date.
Researchers from the university of Hyderabad and IIT Hyderabad has received a patent for a new way to make very thin sheet like materials called TMDCs. They did it with a special type of laser called a Bessel beam femtosecond laser. This method lets them create ultra thin nano sheets more efficiently.
UOH said the new patented method is faster cheaper and easier to scale up than older ways of making the materials, the invention was made by Sai Santosh Kumar Raavi, Challa Rajendra Kumar, and Moram Sree Satya Bharati from IIT-H, along with senior professor at UOH’S School of Physics, Soma Venugopal Rao.
TMDCs are super thin material used in future electronics, light based devices and photonics. The old way of making these ultra thin TMDCs are usually slow, costly, or hard to do on a large scale. This new method uses a special laser fires extremely short pulses. The laser gently breaks the weak forces that hold TMDCs layers together, w/o changing or damaging the material itself. That lets researchers instantly create clean, high quality, sheets that are just one or few atoms thick.
In the end, the patent cover a new method of using benssel beam femtosecond laser to produce ultra thin TMDCs sheets quickly and cheaply. Its novel and incentive because the laser precisely breaks weak interlayer forces w/o damaging the materials unlike slow or messy existing techniques. If scalable, it has strong commercial value for next generation values.
