The Hidden Cost of Alloying: Disorder-Driven Transport Collapse in TMDs
Michele Pisarra, Clara Rebanal, Enrique Arévalo Rodríguez +19
Alloying in two dimensional semiconductors is widely used to tune bandgaps, yet its implications for charge and energy transport remain poorly understood. Here, we investigate MoS2…
Tuning the low-energy band structure in twisted bilayer WSe2
T. -H. -Y. Vu, O. J. Clark, N. H. Jo +21
Tuning the electronic structures of two-dimensional (2D) material-based heterostructures is of crucial importance for their use in functional next-generation electronics. Here, thr…
Defects, band bending and ionization rings in MoS2
Iolanda Di Bernardo, James Blyth, Liam Watson +5
Chalcogen vacancies in transition metal dichalcogenides are widely acknowledged as both donor dopants and as a source of disorder. The electronic structure of sulphur vacancies in…
Imaging the breakdown and restoration of topological protection in magnetic topological insulator MnBiTe
Qile Li, Iolanda Di Bernardo, Johnathon Maniatis +9
Quantum anomalous Hall (QAH) insulators transport charge without resistance along topologically protected chiral one-dimensional edge states. Yet, in magnetic topological insulator…
Metastable polymorphic phases in monolayer TaTe2
Iolanda Di Bernardo, Joan Ripoll-Sau, Fabian Calleja +6
Polymorphic phases and collective phenomena - such as charge density waves (CDWs) - in transition metal dichalcogenides (TMDs) dictate the physical and electronic properties of the…
Formation of a stable surface oxide in MnBiTe thin films
Golrokh Akhgar, Qile Li, Iolanda Di Bernardo +6
Understanding the air-stability of MnBiTe thin films is crucial for the development and long-term operation of electronic devices based around magnetic topological insulato…
Overcoming Boltzmann's Tyranny in a Transistor via the Topological Quantum Field Effect
Muhammad Nadeem, Iolanda Di Bernardo, Xiaolin Wang +2
The sub-threshold swing is the fundamental critical parameter determining the operation of a transistor in low-power applications such as switches. It determines the fraction of di…
Crossover from 2D ferromagnetic insulator to wide bandgap quantum anomalous Hall insulator in ultra-thin MnBi2Te4
Chi Xuan Trang, Qile Li, Yuefeng Yin +9
Intrinsic magnetic topological insulators offer low disorder and large magnetic bandgaps for robust magnetic topological phases operating at higher temperatures. By controlling the…
Progress in epitaxial thin-film Na3Bi as a topological electronic material
I. Di Bernardo, J. Hellerstedt, C. Liu +8
Na3Bi was the first experimentally verified topological Dirac semimetal (TDS), and is a 3D analogue of graphene hosting relativistic Dirac fermions. Its unconventional momentum-ene…
