Abstract Non-reciprocal electronic transport in a material occurs if both time reversal and inversion symmetries are broken. The superconducting diode effect (SDE) is an exotic manifestation of this type of behavior where the critical current for pos

The quantum spin Hall (QSH) phase is an important feature of two dimensional topological insulators and is typically observed at temperatures below 100 K. Here, the authors report the observation of a room temperature quantum spin Hall phase in few-a

Abstract The highly successful Dirac equation predicts peculiar phenomena such as Klein tunnelling and Zitterbewegung (ZB) of electrons. From its conception by Erwin Schrödinger, ZB has been considered key in understanding relativistic quantum mecha

Spin and orbital freedoms of electrons traveling on spin-resolved quantum Hall edge states (quantum Hall ferromagnets) are maximally entangled. The unitary operations on these two freedoms are hence equivalent, which means one can manipulate the spin

Natural two-dimensional electron gas (2DEG) on the surface of n-type InAs has been used for studying superconductor-semiconductor junctions. For high mobility and easiness in sample design, however, 2DEGs in quantum wells are more favorable. Even at

In the last century the band-gap engineering including modulation doping technique, largely expanded the possibility of solid state devices. The concept of topology came into our view in the beginning of the present century. The first claim of topolo

The Josephson supercurrent in ballistic superconductor/normal metal/superconductor (SNS) junctions is carried through the Andreev bound states (ABS) formed in the normal conductor. These virtual states of traversing electrons and holes are modulated

Magnetic field and spin-orbit interaction (SOI) are representative freedoms that can be entangled to electron spins. In experiments, while magnetic field strong enough for the control of spin is difficult to be localized onto the area for single spin
