Materials Innovation Platforms (MIP)

MIPs embrace the paradigm set forth by the Materials Genome Initiative (MGI) which strives to “discover, manufacture, and deploy advanced materials in half the time and at a fraction of the cost.”  Platforms respond to the increasing complexity of conducting materials research that requires the close collaboration of multidisciplinary teams who have access to cutting edge tools.
The 2DCC-MIP is funded by NSF cooperative agreement DMR-1539916.

Intrinsic Antiferromagnetic Topological Insulator MnBi2Te4 - Towards Realization of High-Temperature Quantum Anomalous Hall Insulator


Quantum anomalous Hall (QAH) insulators hold great promise for applications in energy efficient electronics and quantum computation, since it supports spin-polarized dissipation-less chiral edge states. To date, the fully developed QAH state has only been realized in magnetically doped topological insulator (TI) [i.e. Cr/V doped (Bi,Sb)2Te3] films at a ‘critical temperature’ below ~ 1K, which severely constrains both the exploration of fundamental physics and meaningful technological applications based on this exotic phenomenon. Theory has shown that an intrinsic magnetic topological insulator MnBi2Te4 is an ideal platform to realize high-temperature QAH insulator and this prediction has attracted a great deal of interest. In this talk, I will discuss our studies on the spin scattering and non-collinear spin structure induced the intrinsic anomalous Hall effect probed in magnetotransport measurements.
