Zener tunnelling in biased bilayer graphene via analytic continuation of semiclassical theory
Harley Scammell, Oleg P. Sushkov
Employing a semiclassical method based on analytic continuation, we compute the electron-hole pair production rate in biased bilayer graphene subject to an in-plane electric field.…
Screening of the band gap in electrically biased bilayer graphene: From Hartree to Hartree-Fock
Jack N. Engdahl, Zeb E. Krix, Oleg P. Sushkov
It is well known that a direct band gap may be opened in bilayer graphene via the application of a perpendicular electric field (bias). The bias and the chemical potential are cont…
Transverse magnetic focusing in two-dimensional hole gases
Yik K. Lee, Jackson S. Smith, Hong Liu +4
Two-dimensional hole gases (2DHGs) have strong intrinsic spin-orbit coupling and could be used to build spin filters by utilising transverse magnetic focusing (TMF). However, with…
Quantum magnetic oscillations in the absence of closed electron trajectories
Z. E. Krix, O. A. Tkachenko, V. A. Tkachenko +4
Quantum magnetic oscillations in crystals are typically understood in terms of Bohr-Sommerfeld quantisation, the frequency of oscillation is given by the area of a closed electron…
Artificial electrostatic crystals: a new platform for creating correlated quantum states
Daisy Q. Wang, Zeb Krix, Olga A. Tkachenko +7
The electronic properties of solids are determined by the crystal structure and interactions between electrons, giving rise to a variety of collective phenomena including supercond…
Probing Fermi surface parity with spin resolved transverse magnetic focussing
M. J. Rendell, S. D. Liles, S. Bladwell +6
Measurements of the Fermi surface are a fundamental technique for determining the electrical and magnetic properties of solids. In 2D systems, the area and diameter of the Fermi su…
Electrical control of the Zeeman spin splitting in two-dimensional hole systems
Elizabeth Marcellina, Ashwin Srinivasan, Dmitry Miserev +6
Semiconductor holes with strong spin-orbit coupling allow all-electrical spin control, with broad applications ranging from spintronics to quantum computation. Using a two-dimensio…
Mechanisms for strong anisotropy of in-plane g-factors in hole based quantum point contacts
D. S. Miserev, A. Srinivasan, O. A. Tkachenko +5
In-plane hole g-factors measured in quantum point contacts based on p-type heterostructures strongly depend on the orientation of the magnetic field with respect to the electric cu…
Dimensional reduction of the Luttinger Hamiltonian and g-factors of holes in symmetric two-dimensional semiconductor heterostructures
D. S. Miserev, O. P. Sushkov
The spin-orbit interaction of holes in zinc-blende semiconductors is much stronger than that of electrons. This makes the hole systems very attractive for possible spintronics appl…
Effects of Coulomb screening and disorder on artificial graphene based on nanopatterned semiconductor
O. A. Tkachenko, V. A. Tkachenko, I. S. Terekhov +1
A residual disorder in the gate system is the main problem on the way to create artificial graphene based on two-dimensional electron gas. The disorder can be significantly screene…
Topological Insulating States in Laterally Patterned Ordinary Semiconductors
O. P. Sushkov, A. H. Castro Neto
We propose that ordinary semiconductors with large spin-orbit coupling (SOC), such as GaAs, can host stable, robust, and {\it tunable} topological states in the presence of quantum…
