A Brillouin light scattering study of the spin-wave magnetic field dependence in a magnetic hybrid system made of an artificial spin-ice structure and a film underlayer
F. Montoncello, M. T. Kaffash, H. Carfagno +3
We present a combined Brillouin light scattering and micromagnetic simulation investigation of the magnetic-field dependent spin-wave spectra in a hybrid structure made of permallo…
Epitaxial growth of atomically thin Ga2Se2 films on c-plane sapphire substrates
Mingyu Yu, Lottie Murray, Matthew Doty +1
Broadening the variety of two-dimensional (2D) materials and improving the synthesis of ultrathin films are crucial to the development of the semiconductor industry. As a state-of-…
Surface plasmon-phonon-magnon polariton in a topological insulator-antiferromagnetic bilayer structure
D. Quang To, Zhengtianye Wang, Yongchen Liu +6
We present a robust technique for computationally studying surface polariton modes in hybrid materials. We use a semi-classical model that allows us to understand the physics behin…
Strong coupling between a topological insulator and a III-V heterostructure at terahertz frequency
D. Quang To, Zhengtianye Wang, Q. Dai Ho +8
We probe theoretically the emergence of strong coupling in a system consisting of a topological insulator (TI) and a III-V heterostructure using a numerical approach based on the s…
Principles of spintronic THz emitters
Weipeng Wu, Charles Yaw Ameyaw, Matthew F. Doty +1
Significant progress has been made in answering fundamental questions about how and, more importantly, on what time scales interactions between electrons, spins, and phonons occur…
Electronic Structure and Small Hole Polarons in YTiO3
Jin Yue, Nicholas F. Quackenbush, Iflah Laraib +10
As a prototypical Mott insulator with ferromagnetic ordering, YTiO3 (YTO) is of great interest in the study of strong electron correlation effects and orbital ordering. Here we rep…
Investigation of spin orbit torque driven dynamics in ferromagnetic heterostructures
Xinran Zhou, Hang Chen, Yu-Sheng Ou +5
We use time-resolved (TR) measurements based on the polar magneto-optical Kerr effect (MOKE) to study the magnetization dynamics excited by spin orbit torques in Py (Permalloy)/Pt…
Hole Spin Mixing in InAs Quantum Dot Molecules
M. F. Doty, J. I. Climente, A. Greilich +2
Holes confined in single InAs quantum dots have recently emerged as a promising system for the storage or manipulation of quantum information. These holes are often assumed to have…
Antibonding ground states in semiconductor artificial molecules
M. F. Doty, J. I. Climente, M. Korkusinski +4
The spin-orbit interaction is a crucial element of many semiconductor spintronic technologies. Here we report the first experimental observation, by magneto-optical spectroscopy, o…
Engineering electron and hole tunneling with asymmetric InAs quantum dot molecules
A. S. Bracker, M. Scheibner, M. F. Doty +6
Most self-assembled quantum dot molecules are intrinsically asymmetric with inequivalent dots resulting from imperfect control of crystal growth. We have grown vertically-aligned p…
Electrically tunable g-factors in quantum dot molecular spin states
M. F. Doty, M. Scheibner, I. V. Ponomarev +5
We present a magneto-photoluminescence study of individual vertically stacked InAs/GaAs quantum dot pairs separated by thin tunnel barriers. As an applied electric field tunes the…
