Helping You Succeed in Nano-Science

Develop Your Path at Nanoscale with Us


Albanova Nanolab is the key resource for academic and commercial nanoscale R&D in the Stockholm area. With close to 80 unique users in 2019, a super-efficient economic model and flexible infrastructure, it offers broad-spectrum, affordable access to top-level nano-fabrication tools and processes. ANL is a part of the national network for micro- and nano-fabrication MYFAB, together with KTH-Electrum, CTH-MC2, UU-Ångström, and LU-Nanolab, and is ideally suited to basic research and high-risk innovation.

ANL has seen steady, organic growth over many years and we see a future with increasing the number of users and projects, especially in view of the coming relocation to Albanova of ca 80 nano-scientists from KTH-Kista early in 2020, as well as SU’s expansion of their Quantum Technology footprint at the vastly expanded Albanova Science Centre. Our plan is to continue to play a key role in making sure our users stay at the forefront of the internationally competitive nano-scale R&D.


Nano-patterning

We emphasize direct-writing methods for patterning, especially E-beam and Focused-ion-beam lithography (EBL&FIB), but also direct-write photo-lithography, as opposed to mask-based lithography. This saves time and money with our small-series nano-device research and small-series prototyping. 

 

 


Materials Fabrication

Our specialty are films and multilayers by sputtering and evaporation. We work with a wide variety of materials, with cross-usage requirements that are not as stringent as in many specialized-process labs. Our proof-of-concept environment is ideally suited to academic research as well as various startups and spinoffs in the nano-tech area.


Process Integration

Our users have access to various etching systems capable of sample cryo-cooling; processes based on various resists, surface profilometers, optical microscopes, ovens, chip bonders, probe stations, and various other tools. Additionally, we offer a versatile lineup of AFM microscopes and an EDX system for chemical analysis.

 

Single Quantum


Single Quantum, a spinoff from the Zwiller group (KTH-APhys), commercializes high-performance single-photon detectors based on superconducting nanostructures. The outstanding superconducting film deposition and nano-patterning processes available at KTH-ANL enable joint R&D of KTH and Single Quantum on developing a new generation of single-photon detectors with the time resolution, noise level, and detection efficiencies setting new standards in quantum optics [1]. The application space is the booming quantum communications, where SQ is one of the fastest growing start-ups internationally.

Intermodulation Products


KTH-ANL hosts the biggest and most versatile atomic force microscopy (AFM) lab in Sweden. Thanks to this rich and flexible environment, Intermodulation Products AB was founded as a spinoff of the Haviland group (KTH-APhys). Intermodulation Products AB commercializes add-on equipment to labs and users who want to extend the measurement capabilities of their AFM with mechanical, electrical and magnetic characterization, for applications ranging from energy materials to life sciences. All the special modes developed by Intermodulation Products are available to users of the KTH-ANL AFMs. The start-up is actively expanding its products space, e.g. to high-speed multi-frequency lock-in systems.
