X-ray spectroscopic study of BaFeO thin films; an Fe ferromagnetic insulator
T. Tsuyama, T. Matsuda, S. Chakraverty +7
We investigated the electronic and magnetic properties of fully oxidized BaFeO3 thin films, which show ferromagnetic-insulating properties with cubic crystal structure, by hard x-r…
Electrically Tunable Optical Absorption in a Graphene-based Salisbury Screen
Vrinda Thareja, Juhyung Kang, Hongtao Yuan +4
We demonstrate a graphene-based Salisbury screen consisting of a single layer of graphene placed in close proximity to a gold back reflector. The light absorption in the screen can…
Broadband Linear-Dichroic Photodetector in a Black Phosphorus Vertical p-n Junction
Hongtao Yuan, Xiaoge Liu, Farzaneh Afshinmanesh +12
The ability to detect light over a broad spectral range is central for practical optoelectronic applications, and has been successfully demonstrated with photodetectors of two-dime…
Visible light enhanced field effect at LaAlO3/SrTiO3 interface
Y. Lei, Y. Z. Chen, Y. W. Xie +8
Electrical field and light-illumination have been two most widely used stimuli in tuning the conductivity of semiconductor devices. Via capacitive effect electrical field modifies…
The potential profile at the LaAlO3/SrTiO3 (001) heterointerface in operando conditions
M. Minohara, Y. Hikita, C. Bell +7
We report measurements of the gate-bias dependent band alignment, especially the confining potential profile, at the conducting LaAlO3/SrTiO3 (001) heterointerface using soft and h…
Quantum longitudinal and Hall transport at the LaAlO3/SrTiO3 interface at low electron densities
Yanwu Xie, Christopher Bell, Minu Kim +3
We examined the magneto-transport behavior of electrons confined at the conducting LaAlO3/SrTiO3 interface in the low sheet carrier density regime. We observed well resolved Shubni…
