Atomic Resolution Imaging at 2.5 GHz using Near Field Microwave Microscopy

Facilities

Sub-nanometer probes of surfaces provide important information about chemical and physical properties of materials at atomic level.  Microwave microscopy (left) is used to study materials properties at GHz (109 sec-1). This is the frequency range relevant for computers and cell phones, for which the materials are being explored.

EXAFS Studies of Local Structure in MTJ

Research

Background: CoFeB-MgO magnetic tunnel junctions (MTJs) are leading spintronic devices that relies on quantum Mechanical tunneling of electrons from one magnetic metal (CoFeB) to another across an insulating barrier of MgO. The electrical resistance of such MTJs is dictated by the orientation of the two CoFeB metals, parallel or antiparallel.

High School Student Research Internships at the Johns Hopkins

Research

Background: The JHU MRSEC conducts extensive K-12 educational outreach programs aimed at promoting interest in and awareness of the importance of modern materials research. High school students from the greater Baltimore area receive four-week internships each July to conduct research in the laboratories of the JHU MRSEC. The students are
