Charge doping and large lattice expansion in oxygen-deficient heteroepitaxial WO3
Giordano Mattoni, Alessio Filippetti, Nicola Manca +2
Tungsten trioxide is a versatile material with widespread applications ranging from electrochromic and optoelectronic devices to water splitting and catalysis of chemical reactions…
Balanced electron-hole transport in spin-orbit semimetal SrIrO3 heterostructures
Nicola Manca, Dirk J. Groenendijk, Ilaria Pallecchi +7
Relating the band structure of correlated semimetals to their transport properties is a complex and often open issue. The partial occupation of numerous electron and hole bands can…
Superconducting quantum point contact with split gates in the two dimensional LaAlO3/SrTiO3 superfluid
Holger Thierschmann, Emre Mulazimoglu, Nicola Manca +3
One of the hallmark experiments of quantum transport is the observation of the quantized resistance in a point contact formed with split gates in GaAs/AlGaAs heterostructures. Bein…
Spin-orbit semimetal SrIrO in the two-dimensional limit
D. J. Groenendijk, C. Autieri, J. Girovsky +10
We investigate the thickness-dependent electronic structure of ultrathin SrIrO and discover a transition from a semimetallic to a correlated insulating state below 4 unit cells…
Enhancement of electron mobility at oxide interfaces induced by WO3 overlayers
Giordano Mattoni, David J. Baek, Nicola Manca +4
Interfaces between complex oxides constitute a unique playground for 2D electron systems (2DES), where superconductivity and magnetism can arise from combinations of bulk insulator…
Selective high frequency mechanical actuation driven by the VO2 electronic instability
Nicola Manca, Luca Pellegrino, Teruo Kanki +6
Micro- and nano-electromechanical resonators are a fundamental building block of modern technology, used in environmental monitoring, robotics, medical tools as well as fundamental…
Programmable Mechanical Resonances in MEMS by Localized Joule Heating of Phase Change Materials
Nicola Manca, Luca Pellegrino, Teruo Kanki +4
A programmable micromechanical resonator based on a VO2 thin film is reported. Multiple mechanical eigenfrequency states are programmed using Joule heating as local power source, g…
Reversible oxygen vacancies doping in (La,Sr)MnO microbridges by combined self-heating and electromigration
Nicola Manca, Luca Pellegrino, Daniele Marré
Combination of electric fields and Joule self-heating is used to change the oxygen stoichiometry and promote oxygen vacancy drift in a free-standing thin fi…
Influence of thermal boundary conditions on the current-driven resistive transition in microbridges
Nicola Manca, Teruo Kanki, Hidekazu Tanaka +2
We investigate the resistive switching behaviour of microbridges under current bias as a function of temperature and thermal coupling with the heat bath. Upon incre…
