Facilities

We have two electrical probe stations that allow us to measure longitudinal and transverse resistances in Hall bar devices using a lock-in technique. Both setups are complemented with a constant ac/dc current source, a pulse generator (1-100 ns, -/+50V), a high voltage source (<1.1 kV), an arbitrary waveform generator, and a high speed advanced oscilloscope. 

The 2D-heterostructure transfer system allows the transfer of exfoliated layered materials onto surfaces of various substrates and consists of fully motorized micro-manipulators with a total of 8 degrees of freedom and operate under a high resolution microscope with variable substrate temperature (from room temperature up to around 150ºC).

We have two Magneto-optic Kerr Effect (MOKE) setups operating in wide-field (WF) and scanning laser (SL) modes, respectively.  Both setups are complemented with relevant current sources (ac/dc/pulse), enabling us to study current-driven magnetization dynamics.

Being part of ICMAB, our research group has access to all the Scientific and Technical services of the Institute and those of the neighbouring institutes integrated within the Barcelona Nanocluster in Bellaterra (BNC-b), a research network that includes the UAB, the CSIC (ICMAB, IMB-CNM and ICN2) and IRTA, part of the UAB Research Park of the Universitat Autònoma de Barcelona (PRUAB) and the ALBA Synchrotron. 

We have a dual-chamber magnetron sputtering tool with DC and RF deposition capabilities. The chambers are dedicated to metal and oxide deposition, respectively, with a separate load lock. We can deposit from two different targets simultaneously (co-deposition) in both chambers, and they can operate independently.

We have an ultrasonic wedge bonder (West Bond 7476E Wedge), designed to interconnect micron-scale wire leads between chip carriers and devices. The machine can bond aluminum or gold wires of ranging diameter (typically 25 um).
