Engineering quantum wires states on hydrogen terminated silicon for atom scale circuitry
Recent advances in hydrogen lithography on silicon surfaces now enable the fabrication of complex and error-free atom-scale circuitry. To illustrate these capabilities and highlight the importance of reliable interconnects, two prototype integrated atomic circuits are presented. Central to their operation are continuous atomic wires required to actuate and transmit signals. At this scale, wire geometry is critical because the precise position of each atom determines the resulting electronic structure. A systematic comparison of different wire geometries is therefore essential to identify the most effective configurations for signal transmission.

Introducing ToF MIM
The global electronic band structure and its dynamics are of great interest in quantum materials. Scienta Omicron’s Time-of-Flight Momentum and Imaging Microscope (ToF MIM) is an efficient tool to characterise global electronic band structure and microstructure at once. It is ideally suited to study ultrafast electron dynamics in pump-probe experiments using ultrashort laser pulses.
Sample Manipulators
Open and Closed Cycle Sample Manipulators
When aiming at high experimental energy resolution for ARPES measurement, it is crucial to achieve ultra-low sample temperatures to quench thermal broadening. This is possible with state-of-the-art cryo manipulators reaching sample temperatures from < 3.5 K and featuring up to 6 fully motorized axes for a large range of movements. The manipulators are available as open and closed cycle. Open cycle manipulators reach lower temperature specifications and are rapidly cooled down from room temperature to 10 K in 15 min. The low He consumption below 1 l/h at ultimate temperature and the possibility to operate with liquid nitrogen at higher temperatures ensure a low operating cost. Closed cycle manipulators have no He consumption providing unlimited holding time.

PEAK Slit Control
Optimal analyser settings with remote control
In photoelectron spectroscopy measurements, there is always a trade-off between signal intensity and resolution. Optimising this balance is the key to obtaining smooth and sharp spectra within the shortest time possible. For hemispherical analysers, this trade-off is controlled by the selected entrance slit and pass energy.
PEAK Slit Control replaces manual slit changes at the analyser with a motorised and software-controlled slit. With the control of all analyser settings, easy and quick optimisation of signal intensity versus resolution is possible.
