Superpuddles Lab

In the Superpuddles Lab we focus our research in the two-dimensional (2D) materials and heterostructures of superconductors in complex quantum matter. Our goal is to design superconductors with modular interfaces that can be assembled at atomically precise length scales in order to study and control the emerging topological organization of strongly interacting systems. In our lab we synthetize and isolate atomically thin superconductors, assemble these materials into novel multicomponent-network system and quantitatively interrogate them by means of electronic quantum transport and synchrotron radiation microscopies. We use state-of-the-art micromanipulation and nanofabrication tools for the preparation of mesoscopic structures, and we synthetize the low-dimensional quantum circuits in a cryogenically cooled inert atmosphere.

Equipment

Double purified glovebox-cluster integrating:
- Vibration-isolated cryo-cooled analytical probe-station (controlled temperature range 200 °C to -150 °C) with micromanipulator designed for use within a glove box and with motorized solutions remotely controlled.
- Wirebonder with semi-automatic thermosonic wedge and ball bonder, zoom stereo-microscope, adjustable height temperature controlled stage and digital video targeting.
- Stand-alone platform integrated in the glovebox for the physical vapor deposition of materials under high vacuum conditions (temperature range: 300°C up to 1200°C (1400°C), maximum substrate size 100 x 100 mm with a liquid nitrogen substrate cooling stage and with a ten different targets revolving special source.

Electronic measurement systems:
- Two rack system with home-made design for low-temperature quantum transport measurements
