Science Image Specialist Felice Frankel Teaches Masterclasses on the Visual Communication of Materials Science and Engineering
Nearly 300 postdoctoral researchers and graduate students attended masterclasses on the visual communication of materials science and engineering between October 2013 and January 2014. At programs offered in partnership with the Departments of Mechanical Engineering, Chemical Engineering, and Materials Science and Engineering, Felice Frankel, research specialist at the MIT MRSEC, presented 90-minute talks addressing common errors students and faculty make in the graphics and images used in their presentations and publications.

Observation of Majorana fermions in a ferromagnetic chains on a superconductor

Stevan Nadj-Perge, Ilya K. Drozdov, Jian Li, Hua Chen, Sangjun Jeon, Jungpil Seo, Allan H. MacDonald, B. Andrei Bernevig, and Ali Yazdani.
Topological superconductors are a distinct form of matter that is predicted to host boundary Majorana fermions. These quasi-particles are the emergent condensed matter analogs of the putative elementary spin-1/2 particles originally proposed by Ettore Majorana in the 1930’s with the intriguing property of being their own anti-particles. The search for Majorana quasi-particle bound states in condensed matter systems is motivated in part by their potential use as topological qubits to perform fault-tolerant computation aided by their

Terminator 2 is widely remembered for its metal shape-shifting villain. Impervious to bullets, explosives, and fire, theT-1000 robot was capable of changing shape at will. Researchers at the North Carolina State University have taken a step towards making science fiction a reality by developing a technique for controlling the surface tension of liquid metals using very low voltages. This technology paves the way for shape-reconfigurable metal components in electronic, electromagnetic, and microfluidic devices.

Manipulation of the Hanle curve contour for spin-transport structures in the presence of an ac drive

Robert C. Roundy, Utah MRSEC Graduate Research Associate; Megan C. Prestgard, Utah MRSEC Graduate Research Associate; Ashutosh Tiwari, Associate Professor of Materials Science and Engineering and M. E. Raikh, Associate Professor of Physics at the University of Utah.
Effect: We have demonstrated that the shape of the Hanle curve (non-local resistance versus applied magnetic field) can be manipulated using an ac drive.

Heterogeneously integrated ferroelectric optical modulator on silicon with high Pockels’ coefficient

H. Tang, F. Walker, C. Ahn (Yale University)
The collaboration among Hong Tang, Charles Ahn, and Fred Walker’s groups recently realized a new type of electro-optic modulator based on epitaxial ferroelectric BaTiO3 on silicon. A very high Pockels’ coefficient, up to 213 pm/V, was demonstrated, a record value that is more than six times larger than found in commercial optical modulators based on lithium niobate. The monolithically integrated BaTiO3 optical modulators show modulation bandwidth in the gigahertz regime, which is promising for broadband applications.
