Imaging and tuning polarity at SrTiO3 domain walls
Yiftach Frenkel, Noam Haham, Yishai Shperber +7
Electrostatic fields tune the ground state of interfaces between complex oxide materials. Electronic properties, such as conductivity and superconductivity, can be tuned and then u…
Current-induced nonuniform enhancement of sheet resistance in Ar+ irradiated SrTiO3
Debangsu Roy, Yiftach Frenkel, Sagi Davidovitch +5
The sheet resistance Rs of Ar+ irradiated SrTiO3 in patterns with a length scale of several microns increases significantly below 40 K in connection with driving currents exceeding…
Anisotropic transport at the LaAlO3/SrTiO3 interface explained by microscopic imaging of channel-flow over SrTiO3 domains
Yiftach Frenkel, Noam Haham, Yishai Shperber +6
Oxide interfaces, including the LaAlO3/SrTiO3 interface, have been a subject of intense interest for over a decade due to their rich physics and potential as low dimensional nanoel…
Mechanical control of individual superconducting vortices
Anna Kremen, Shai Wissberg, Noam Haham +3
Manipulating individual vortices in a deterministic way is challenging, ideally, manipulation should be effective, local, and tunable in strength and location. Here, we show that v…
