Si/SiGe QuBus for single electron information-processing devices with memory and micron-scale connectivity function
Ran Xue, Max Beer, Inga Seidler +6
The connectivity within single carrier information-processing devices requires transport and storage of single charge quanta. Our all-electrical Si/SiGe shuttle device, called quan…
How to solve problems in micro- and nanofabrication caused by the emission of electrons and charged metal atoms during e-beam evaporation
Frank Volmer, Inga Seidler, Timo Bisswanger +4
We discuss how the emission of electrons and ions during electron-beam-induced physical vapor deposition can cause problems in micro- and nanofabrication processes. After giving a…
Interplay of Excitonic Complexes in -Doped WSe Monolayers
Sven Borghardt, Jhih-Sian Tu, Takashi Taniguchi +2
WSe monolayers with variable doping are an ideal system to study two-dimensional excitonic complexes. Here, we find that the strongest photoluminescence from bright neutral exc…
Engineering of Neutral Excitons and Exciton Complexes in Transition Metal Dichalcogenide Monolayers through External Dielectric Screening
Sven Borghardt, Jhih-Sian Tu, Florian Winkler +4
In order to fully exploit the potential of transition metal dichalcogenide monolayers (TMD-MLs), the well-controlled creation of atomically sharp lateral heterojunctions within the…
Tuning the valley and chiral quantum state of Dirac electrons in van der Waals heterostructures
J. R. Wallbank, D. Ghazaryan, A. Misra +15
Chirality is a fundamental property of electrons with the relativistic spectrum found in graphene and topological insulators. It plays a crucial role in relativistic phenomena, suc…
Twist-controlled resonant tunnelling in graphene-boron nitride-graphene heterostructures
A. Mishchenko, J. S. Tu, Y. Cao +19
Recent developments in the technology of van der Waals heterostructures made from two-dimensional atomic crystals have already led to the observation of new physical phenomena, suc…
Hierarchy of Hofstadter states and replica quantum Hall ferromagnetism in graphene superlattices
G. L. Yu, R. V. Gorbachev, J. S. Tu +16
Self-similarity and fractals have fascinated researchers across various disciplines. In graphene placed on boron nitride and subjected to a magnetic field, self-similarity appears…
Electronic Properties of Graphene Encapsulated with Different Two-Dimensional Atomic Crystals
A. V. Kretinin, Y. Cao, J. S. Tu +18
Hexagonal boron nitride is the only substrate that has so far allowed graphene devices exhibiting micron-scale ballistic transport. Can other atomically flat crystals be used as su…
