Topological Materials & Interfacial Coupling for Topologically Enabled Devices (TED) - ARL-R-SEDD-300000

Topological Materials & Interfacial Coupling for Topologically Enabled Devices (TED) - ARL-R-SEDD-300000 is sponsored by DEVCOM Army Research Laboratory. This opportunity seeks a research fellow with experience in theoretical/computational modeling and characterization of topological, magnetic materials and heterostructures, to advance the physics of topological materials to the engineering of emerging electronic devices.

Zintellect will be down Saturday, August 29, 2026 beginning at 7 a. m. EDT through 7 p.

m. EDT. Please plan accordingly.

Thank you for your patience. Topological Materials & Interfacial Coupling for Topologically Enabled Devices (TED) DEVCOM Army Research Laboratory The U.S. Army Research Laboratory (ARL) seeks a highly motivated, well informed, cross-disciplinary and skilled research fellow with experience in theoretical/computational modeling and characterization of topological, magnetic materials and heterostructures.

This research fellow will study structural, electronics and magnetic properties of topological insulator (TI)/magenetic material heterosturctures with quantum mechanical first principle method. The topologically protected surface states in TI are insensitive to imperfections in the bulk crystal, and do not backscatter off surface defects.

The interplay of spin-momentum locking and magnetic materials allows one to efficiently switch the conducting surface channel off and on by applying an electric voltage to a TI/ferromagnet heterostructure. Spin-momentum locking is also why TI surface currents carry a net spin that can be used to flip the orientation of magnets.

These phenomena respectively enable new transistor and memory device architectures that smash through the semiconductor power and speed limitations which are ending Moore’s law and Dennard’s scaling. This research fellowship is a critical part of on-going DOD-wide research project on topologically enabled devices (TED).

ARL is accelerating a strategic initiative to move the physics of topological materials to the engineering of emerging electronic devices that may solve future battlefield challenges with ultra-efficient electronics and RF technology, and equivalently may advance related civilian technology.

Recent theoretical predictions for the device concepts based on topological insulator/magentic materials heterstructures far exceed today’s state of the art for things such as sensing, sub-threshold switching with markedly reduced energy consumption, energy harvesting and radio frequency or even THz electronics.

Many of these opportunities can take advantage of topological surface currents and spin-orbit coupling at room temperature even with today’s imperfect materials. This fellowship is a unique opportunity to take full advantage of ARL’s strategic intra-extramural reach with a seamless collaboration among ARL laboratories, extended campuses and leading academic scientists.
