Transfer stage

 The system is custom-built tube lens system with several micromanipulators for stacking of various 2D materials into heterostructures under ambient conditions. The sample/substrate stage has 360 degree centric rotation feature with below 0.1 degree precision, and controllable heating option. Stamp carrying stage has five degrees of freedom, xyz translation, tilt, and pitch. Lateral precision for the stacking of flakes is usually below 1 micrometer. The system is also used for silver epoxy based bonding of the devices.

Nabertherm Compact tube furnace

The furnace is employed in a chemical vapor deposition (CVD) setup targeting the growth of TMDCs on various substrates, as well as for recrystallizing and initiating phase transitions in phyllosilicates. The setup is equipped with Ar/H2 carrier gasses, and sulfur/selenium sources. The system is designed for both dry and wet transition metal precursor use, and is connected to an Ar/low-vacuum glovebox for sample exchange.

Instec Microprobe Station 

The micro probe station operates under ambient or under low vacuum (1e-2 mbar), with four Au/Pd probes, and sample cooling/heating stage. It can operate under liquid nitrogen (77 K) and up to 673 K. The system is connected to a Kethley dual-source unit, and is dedicated mainly for characterizing the electrical properties of 2D materials-based devices. The system can be combined with external permanent magnets, reaching up to 120 mT fields in an out-of-plane configuration. Further, the system is possible to combine with confocal microscopes of spectroscopic setups. This can allow for e.g. for simultaneous Raman and transport measurements, or measurements of electroluminescence.
