Saidur Rahman Bakaul

Assistant Materials Scientist

I am interested in interdisciplinary research at the intersection of materials science and electronic engineering

Biography

I am a Principal Investigator in the Materials Science Division, leading the works on ferroelectric and multiferroic materials and activities related to the scanning probe microscopy. I invented the Layer Transfer Technique to create freestanding ultrathin films of single-crystalline complex oxide materials. I have deep experience in semiconductor, ferroic, and superconducting materials and devices. My current research is mostly focused on exploring local electronic, piezoelectric and thermal properties of freestanding complex oxide materials that can be utilized in beyond-CMOS microelectronic logic, memory and sensing devices. My ongoing research also encompasses 2-D and binary oxide ferroelectric materials and emerging electromechanical phenomena that arise due to the intricate structure-polarization relationship.
