Atom probe tomography for 3D discovery

The Nobel Prize in Physics 2014 was shared by UCSB Professor Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".  Professor Nakamura is a major user of the Shared Experimental Facilities of the UCSB MRSEC, co-authoring multiple publications every year that acknowledge the NSF-MRSEC grant number DMR 1121053.  

On November 10 and 17, 2015, 18 teachers visited the Princeton Center for Complex Materials as part of Teacher Prep's program to learn about materials science and how to apply it to the classroom. This unique PCCM program is part of a larger "Teachers as Scholars" initiative as part of Princeton University's Teacher Preparation program.

MRSEC faculty at Princeton University and the University of Delaware co-hosted a virtual symposium celebrating early-career researchers in Soft and Biological Matter with a focus on those from underrepresented groups.

Novel Multidimensional Visible Light Spectroscopy Tracks Optical Excitations

A conventional laser consists of three main components: a gain medium, a cavity, and an energy source. Researchers at Princeton and the University of Maryland Joint Quantum Institute have demonstrated a nanoscale laser that is driven by a single electron tunneling events.

Magnetic materials are vital in technologies from spintronics to biomedicine. Coupling magnetism with optical responses broadens their utility to sensing, magneto-optical memory, and optical isolation. Chromium chalcogenide spinels display particularly rich magnetism and magneto-optical properties. Colloidal nanocrystals (NCs) offer routes to solution-processing, heterointegration, and property modulation through size, shape, or heterostructure control, but many chalcogenide spinels have never been synthesized at the nanoscale, and little control over size or morphology has been demonstrated.

Grain boundaries, interfaces between two crystals inside a material, are important defects which can dramatically alter material response because the structure of the boundary is different from the bulk crystalline region.
