Supercurrent mediated by helical edge modes in bilayer graphene
Prasanna Rout, Nikos Papadopoulos, Fernando Peñaranda +5
Bilayer graphene encapsulated in tungsten diselenide can host a weak topological phase with pairs of helical edge states. The electrical tunability of this phase makes it an ideal…
Stabilizing the inverted phase of a WSe/BLG/WSe heterostructure via hydrostatic pressure
Máté Kedves, Bálint Szentpéteri, Albin Márffy +8
Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin--orbit interaction (SOI) induced by the proxi…
Tunable Photodetectors via in situ Thermal Conversion of TiS to TiO
Foad Ghasemi, Riccardo Frisenda, Eduardo Flores +11
In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. Howev…
Multi-terminal electronic transport in boron nitride encapsulated TiS nanosheets
Nikos Papadopoulos, Eduardo Flores, Kenji Watanabe +7
We have studied electrical transport as a function of carrier density, temperature and bias in multi-terminal devices consisting of hexagonal boron nitride (h-BN) encapsulated tita…
Symmetry breakdown in franckeite: spontaneous strain, rippling and interlayer moiré
Riccardo Frisenda, Gabriel Sanchez-Santolino, Nikos Papadopoulos +9
Franckeite is a naturally occurring layered mineral with a structure composed of alternating stacks of SnS2-like and PbS-like layers. Although this superlattice is composed of a se…
Tunneling spectroscopy of localized states of barriers in vertical van der Waals heterostructures
Nikos Papadopoulos, Pascal Gehring, Kenji Watanabe +3
In transition metal dichalcogenides, defects have been found to play an important role, affecting doping, spin-valley relaxation dynamics, and assisting in proximity effects of spi…
Weak localization in boron nitride encapsulated bilayer MoS
Nikos Papadopoulos, Kenji Watanabe, Takashi Taniguchi +2
We present measurements of weak localization on hexagonal boron nitride encapsulated bilayer MoS. From the analysis we obtain information regarding the phase-coherence and the…
Large birefringence and linear dichroism in TiS3 nanosheets
Nikos Papadopoulos, Riccardo Frisenda, Robert Biele +7
TiS3 nanosheets have proven to be promising candidates for ultrathin optoelectronic devices due to their direct narrow band-gap and the strong light-matter interaction. In addition…
Investigating laser induced phase engineering in MoS2 transistors
Nikos Papadopoulos, Joshua O. Island, Herre S. J. van der Zant +1
Phase engineering of MoS2 transistors has recently been demonstrated and has led to record low contact resistances. The phase patterning of MoS2 flakes with laser radiation has als…
Efros-Shklovskii variable range hopping and nonlinear transport in 1T/1T-MoS
Nikos Papadopoulos, Gary A. Steele, Herre S. J. van der Zant
We have studied temperature- and electric-field dependent carrier transport in single flakes of MoS treated with n-butyllithium. The temperature dependence of the four-termin…
Raman spectroscopy of graphene at high pressure: substrate and pressure transmitting media effects
K. Filintoglou, N. Papadopoulos, J. Arvanitidis +7
The pressure evolution of the Raman spectrum of graphene grown by chemical vapour deposition on polycrystalline copper is investigated with the use of a polar and a non-polar press…
