More Information:


In modern computing, the Boolean logic operations are implemented by interconnect schemes between the transistors. As the miniaturization in the component level to enhance the computational power is rapidly approaching physical limits, and non-zero off-state leakage current limits the energy efficiency of CMOS-based digital circuits, alternative computing devices and methods are vigorously pursued. Towards this, micro/nano-mechanical resonator based dynamic logic/memory elements have revitalized the notion of mechanical computing as it presents intriguing possibilities, such as: ultra-low power consumption, parallel computation, run-time re-co​nfigurability, and reversible computing. This talk will present our recent works on energy efficient electromechanical logic/memory devices built on tunable micro/nano-resonators and progress towards realizing complex logic circuits.



Dr. Md Abdullah Al Hafiz received the B.Sc. (Engg) degree in electrical and electronics engineering from the Islamic University of Technology (IUT), Dhaka, Bangladesh, in 2001, and the Ph.D. degree in electrical engineering from the University of New South Wales (UNSW), Sydney, Australia, in 2011. He joined Prof. Mohammad Younis’sNano/Micro Mechanics and Motion (NM3) Laboratory, PSE division, KAUST, as a Post-Doctoral Fellow in 2014 where he is currently working as a Research Scientist. He is leading a research project focusing on building next generation of energy efficient computing elements (Logic/Memory) based on tunable micro/nano-resonators and published in several high impact journals/conferences (Nature Communications, Nanoscale, Physics Letters A, and JMEMS). His current research areas include M/NEMS devices, micro/nano-fabrication, dynamics of micro/nano-resonators, memory/logic devices, RF-filters, sensors and actuators.
