Debismita Dutta is a 3rd year PhD student at the Advanced Materials and Surfaces Group, Tyndall National Institute, University College Cork, Ireland. She studies Aurivillius phase multiferroic thin films for novel data storage applications in her research project funded by Science Foundation Ireland. Magnetoelectric multiferroics are a type of material that showcase coupled ordered parameters of ferroelectricity and ferromagnetism. In essence, their magnetic polarization can be switched with an electric field, and vice versa, in a manner that retains the switched state even in the absence of the said field- hence becoming 'memory'. These materials also hold potential for devices with multiple memory states, which can store and process more than 8 times the amount of data in the same volume of thin film than current devices. Her work focuses on optimizing industry-relevant synthesis processes like DLI-CVD (Direct Liquid Injection-Chemical Vapor Deposition) to tackle the synthesis challenges that stand in the way of realizing a device roadmap for multiferroic devices. She uses Scanning Probe Microscopy techniques like Piezoresponse Force Microscopy (PFM), Variable Field PFM, Scanning Kelvin Probe Microscopy (SKPFM) and Atomic Force Microscopy (AFM) to study the grain, domain, and multiferroic characteristics of Aurivillius phase thin films.

Biography: Debismita is an Indian researcher who is passionate about exploring exciting new physics in materials by manoeuvring their chemical morphology. She holds a B.Tech in Chemical Engineering and has been very curious about materials research since her undergraduate days. Having done multiple competitive research internships in institutes like National Chemical Laboratory (NCL), as well as Korea Institute of Science and Technology (KIST), she knew she wanted to do a PhD. in materials science. Now she works in Micro Nano Systems in Tyndall National Institute under the supervision of Dr. Lynette Keeney and Dr. Michael Nolan in an SFI funded project. Besides her research, she also enjoys participating in public engagement events, some of which include Famelab Ireland, where she was a national finalist, and 3 Minute Thesis (3MT), where she was the university runner up. She enjoys talking about her work, and would love to discuss her research with you over email or on her social media handles listed below.
