Observation and origin of the -manifold in Si:P -layers
Ann Julie Holt, Sanjoy K. Mahatha, Raluca-Maria Stan +9
By creating a sharp and dense dopant profile of phosphorus atoms buried within a silicon host, a two-dimensional electron gas is formed within the dopant region. Quantum confinemen…
Layer and orbital interference effects in photoemission from transition metal dichalcogenides
Habib Rostami, Klara Volckaert, Nicola Lanata +10
In this work, we provide an effective model to evaluate the one-electron dipole matrix elements governing optical excitations and the photoemission process of single-layer (SL) and…
Momentum-resolved linear dichroism in bilayer MoS
Klara Volckaert, Habib Rostami, Deepnarayan Biswas +19
Inversion-symmetric crystals are optically isotropic and thus naively not expected to show dichroism effects in optical absorption and photoemission processes. Here, we find a stro…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
The Sub-band Structure of Atomically Sharp Dopant Profiles in Silicon
Federico Mazzola, Chin-Yi Chen, Rajib Rahman +7
The downscaling of silicon-based structures and proto-devices has now reached the single atom scale, representing an important milestone for the development of a silicon-based quan…
Direct observation of minibands in twisted heterobilayers
Søren Ulstrup, Roland J. Koch, Simranjeet Singh +8
Stacking two-dimensional (2D) van der Waals materials with different interlayer atomic registry in a heterobilayer causes the formation of a long-range periodic superlattice that m…
Nanoscale patterning of quasiparticle band alignment
Søren Ulstrup, Cristina E. Giusca, Jill A. Miwa +10
Control of atomic-scale interfaces between materials with distinct electronic structures is crucial for the design and fabrication of most electronic devices. In the case of two-di…
Transient Hot Electron Dynamics in Single-Layer TaS
Federico Andreatta, Habib Rostami, Antonija Grubišić Čabo +12
Using time- and angle-resolved photoemission spectroscopy, we study the response of metallic single layer TaS in the 1H structural modification to the generation of excited car…
Epitaxial single layer NbS on Au(111): synthesis, structure, and electronic properties
Raluca-Maria Stan, Sanjoy K. Mahatha, Marco Bianchi +4
We report on the epitaxial growth of single layer NbS on Au(111) and determine both its crystalline and electronic structure by a combination of low-energy electron diffraction…
