Speaker:  Dr. Jeongmin Hong 
Time:      July 10, 10:00am-11:00am.
Location: Room 1A-200, SIST Building

A current emerging field of nanotechnology focus on energy efficient electronics by integration of multifunctional nanomaterials using state-of-the-art nanofabrication processes. Recent years, there has been a resurgence of interest in spin transfer torque devices, 2D nanomagnet, and 3D magneto-electronics. To engineer advanced nano-scale devices for the technology, new concepts are necessary for the further development. In this talk, I will explain a recent development of probe-based information processing systems which require two core components: multi-functional nanoprobes with low energy spin devices and 2D nanomagnet as spin sources followed by recent experimental results of energy efficient nanomagnetic memory bits. I will briefly talk about a 3D device application using the nanoprobes afterwards.


Jeongmin Hong is an engineering director at JS Nanotechnologies, San Jose CA USA which spun off from UC Berkele and Lawrence Berkeley National Lab. Until March of 2017, he was a project scientist at the University of California and E. O. Lawrence Berkeley National Lab, Berkeley CA USA where he proved minimum energy dissipation of nanomagnetic memory bits and low energy spin switching using sub-10-nm magnets. His current research has focused on developing the Spin Transfer Torque based logic devices using Magnetic Tunneling Junctions (STT-MTJs) and investigating new functional magnetic materials for next generation advanced electronics and medical applications using synchrotron radiation. More recently, he has been leading the development of sub-10-nm probe-based MTJs with extremely low energy. He is the author of over 30 papers and has 2 filed patents on the primary topic of Nanotechnology. He serves as an editorial board member for Scientific Reports and Public Library of Science One and a panel reviewer for National Science Foundation (NSF) and American Association for the Advancement of Science (AAAS). He got M.S. from Rensselaer Polytechnic Institute, Troy NY and Ph.D. from the University of California-Riverside, CA, respectively. He was a graduate researcher from NSF funded MRSEC center (led by Prof. Haddon and de Heer) at the University of California, Riverside,CA, where he worked on magnetic and electric properties of carbon nano-structures and state-of-the-art technology of magnetic materials/devices. In 2013, he had a NSF-STC postdoctoral fellowship which is one of the largest centers supported by NSF in the States.
