Enhanced metal-insulator transition in freestanding VO2 down to 5 nm thickness
Kun Han, Liang Wu, Yu Cao +9
Ultrathin freestanding membranes with a pronounced metal-insulator transition (MIT) provides huge potential in future flexible electronic applications as well as a unique aspect of…
Transmission Helium Ion Microscopy of Graphene
Karen L. Kavanagh, Aleksei Bunevich, Mallikarjuna Rao Motapothula
We compare transmission He ion microscopy (HIM) to transmission electron microscopy (TEM) of graphene support films. We present spot transmission patterns that compare with scatter…
Room Temperature Giant Charge-to-Spin Conversion at SrTiO3/LaAlO3 Oxide Interface
Yi Wang, Rajagopalan Ramaswamy, M. Motapothula +5
Two-dimensional electron gas (2DEG) formed at the interface between SrTiO3 (STO) and LaAlO3 (LAO) insulating layer is supposed to possess strong Rashba spin-orbit coupling. To date…
Electron Accumulation and Emergent Magnetism in LaMnO3/SrTiO3 Heterostructures
Zuhuang Chen, Zhanghui Chen, Z. Q. Liu +19
Emergent phenomena at polar-nonpolar oxide interfaces have been studied intensely in pursuit of next-generation oxide electronics and spintronics. Here we report the disentanglemen…
A study of small impact parameter ion channeling effects in thin crystals
M. Motapothula, M. B. H. Breese
We have recorded channeling patterns produced by 1 to 2 MeV protons aligned with <111> axes in 55 nm thick silicon crystals which exhibit characteristic angular structure for defle…
Experimental study of extrinsic spin Hall effect in CuPt alloy
Rajagopalan Ramaswamy, Yi Wang, Mehrdad Elyasi +4
We have experimentally studied the effects on the spin Hall angle due to systematic addition of Pt into the light metal Cu. We perform spin torque ferromagnetic resonance measureme…
