Simultaneous conduction and valence band quantisation in ultra-shallow, high density doping profiles in semiconductors

F. Mazzola, J. W. Wells, A. C. Pakpour-Tabrizi +4

We demonstrate simultaneous quantisation of conduction band (CB) and valence band (VB) states in silicon using ultra-shallow, high density, phosphorus doping profiles (so-called Si…

Stabilization of Polar Nano Regions in Pb-free ferroelectrics

A. Pramanick, W. Dmowski, T. Egami +7

Formation of polar nano regions through solid-solution additions are known to enhance significantly the functional properties of ferroelectric materials. Despite considerable progr…

Contact-Induced Semiconductor-to-Metal Transition in Single-Layer WS

Maciej Dendzik, Albert Bruix, Matteo Michiardi +6

Low-resistance ohmic contacts are a challenge for electronic devices based on two-dimensional materials. We show that an atomically precise junction between a two-dimensional semic…

Giant spin-splitting and gap renormalization driven by trions in single-layer WS/h-BN heterostructures

Jyoti Katoch, Søren Ulstrup, Roland J. Koch +9

In two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), new electronic phenomena such as tunable band gaps and strongly bound excitons and trions emerge fro…

Electron-Phonon Coupling and Surface Debye Temperature of BiTe(111) from Helium Atom Scattering

Anton Tamtögl, Patrick Kraus, Nadav Avidor +9

We have studied the topological insulator BiTe(111) by means of helium atom scattering. The average electron-phonon coupling of BiTe(111) is determined by adapt…

Experimental evidence for pressure-induced first order transition in cerium nitride from B1 to B10 structure type

Morten B. Nielsen, Davide Ceresoli, Jens-Erik Jørgensen +3

The crystal structure of CeN was investigated up to pressures of 82 GPa, using diamond anvil cell powder X-ray diffraction in two experiments with He and Si-oil as the pressure tra…
