Two-Dimensional Charge Localization at the Perovskite Oxide Interface
Chi Sin Tang, Shengwei Zeng, Caozheng Diao +7
The effects of atomic-scale disorder and charge (de)localization holds significant importance,and they provide essential insights in unravelling the role that strong and weak corre…
A two-dimensional electron gas based on a 5s oxide with high room-temperature mobility and strain sensitivity
Zexin Feng, Peixin Qin, Yali Yang +15
The coupling of optical and electronic degrees of freedom together with quantum confinement in low-dimensional electron systems is particularly interesting for achieving exotic fun…
Mechanisms of charge transfer and redistribution in LaAlO3/SrTiO3 revealed by high-energy optical conductivity
T. C. Asmara, A. Annadi, I. Santoso +9
In condensed matter physics the quasi two-dimensional electron gas at the interface of two different insulators, polar LaAlO3 on non-polar SrTiO3 (LaAlO3/SrTiO3) is a spectacular a…
Optical conductivity renormalization of graphene on SrTiO due to resonant excitonic effects mediated by Ti 3\textit{d} orbitals
Pranjal Kumar Gogoi, Paolo E. Trevisanutto, Ming Yang +10
We present evidence of a drastic renormalization of the optical conductivity of graphene on SrTiO resulting in almost full transparency in the ultraviolet region. These finding…
Cationic vacancy induced room-temperature ferromagnetism in transparent conducting anatase Ti_{1-x}Ta_xO_2 (x~0.05) thin films
A. Rusydi, S. Dhar, A. Roy Barman +16
We report room-temperature ferromagnetism in highly conducting transparent anatase Ti1-xTaxO2 (x~0.05) thin films grown by pulsed laser deposition on LaAlO3 substrates. Rutherford…
Large spectral weight transfer in optical conductivity of SrTiO induced by intrinsic vacancies
Teguh C. Asmara, Xiao Wang, Iman Santoso +11
The optical conductivity () of SrTiO for various vacancies has been systematically studied using a combination of ultraviolet - vacuum ultraviolet (UV-VUV) reflectivit…
