The first isolation of graphene opens the avenue for new platforms for physics, electronic
engineering, and materials sciences. Among several kinds of synthesis approaches …

Recent studies have intensively examined 2D materials (2DMs) as promising materials for
use in future quantum devices due to their atomic thinness. However, a major limitation …

The quantum Hall effect can be substantially affected by interfacial coupling between the
host two-dimensional electron gases and the substrate, and has been predicted to give rise …

To investigate the effects of the optical field and the Fermi velocity on the transport properties
of spin and valley electrons, we impose a normal/ferromagnetic/normal (N/F/N) quantum …

The semi-source independent quantum walk random number generator (SI-QW-QRNG) is a
cryptographic protocol that extracts a string of true random bits from a quantum random walk …

Due to the observed superconductivity, the alternating twisted trilayer graphene (ATTLG)
has drawn great research interest very recently, in which three single-layered graphene …

Mirror-symmetric twisted trilayer graphene (tTLG) is composed of even-parity twisted bilayer
graphene (tBLG)-like bands and odd-parity Dirac-like bands. Here, we study the mirror …

Using the transfer matrix method, spin-and valley-dependent electron transport properties
modulated by the velocity barrier were studied in the normal/ferromagnetic/normal …

Polytypes of tetralayer graphene (TLG: Bernal, rhombohedral and mixed stacking) offer a
choice of crystalline structures with different symmetries. Among those, mixed-stacking …

Helical conductors with spin-momentum locking are promising platforms for Majorana
fermions. Here we report observation of two topologically distinct phases supporting helical …
