Transport Studies of Atom-Defined Silicon Quantum Devices

Robert Wolkow has an opening for a postdoc with expert knowledge of low temperature, ultra-high vacuum, scanning tunneling microscopy, and or experience with transport studies of semiconductor quantum dot devices.


We have established efficient, AI-automated atom-defined fabrication procedures and have used those to show diverse classical and quantum phenomena can be controlled and probed in this way. This routine access to atom crafted structures provides a game-changing approach to the kind of physics long pursued through normal lithographic means in the study, for example of semiconductor quantum dots and qubits. Our atom-scale approach offers enormous advantages - such as the ability to make any number of identical structures, enormous splitting energies of 100s of meV rather than 100s of micro eV, and clear paths to CMOS integration.

The postdoc will learn our procedures and apply those with our 2 state of the art multi-probe ultra high vacuum tools to exactingly fabricate, image at the atom scale and measure transport properties of proto quantum devices. Examples of planned devices include an atom-defined SET that is free of the stray charge limitations that plague other designs, and, a Pauli spin-blockade magnetometer that can be extremely portable and room temperature operable while requiring only electronic controls (no lasers as for NV center-based sensors).

All of our work is coordinated with Quantum Silicon Inc which stands ready to commercialize our IP. Our academic work has direct connections to emerging applications and as a result, PDFs and students departing from our group have readily secured jobs at QSi, Google, D-Wave and 1-QBit to name some.

The candidate will have most of the following qualifications:

  • PhD in Physics or Chemical Physics or equivalent;
  • Extensive experience in atom resolving ultra high vacuum scanning tunneling or atomic force microscopy;
  • A demonstrated publication record of STM/AFM studies on semiconductor surfaces;
  • Proficiency in LabVIEW and Python;
  • Experience necessary to operate our atomic force and scanning tunneling microscopes and the associated ultra-high vacuum devices to perform expert level, atom-resolved measurements.
  • Experience with nanoscale cryogenic transport measurements

Responsibilities will include:

  • Design and conduct experiments related to the multiprobe STM/AFM analyses of silicon surfaces;
  • Perform complete analysis of the results and prepare presentations, reports and publish papers on the findings;
  • Design and build automated data collection, instrument control, and research solutions;
  • Assist in supervision of graduate and undergraduate students;
  • Contribute to setting research directions and assist in establishing research methods, data evaluation protocols and standards.

The position will be based at the University of Alberta. Our labs are state of the art and we offer a flexible and supportive working environment with competitive wages.

To Apply:

Applicants should briefly state their research experience pertaining to qualifications above, include a detailed CV, and kindly arrange to have three letters of reference forwarded to:

Dr. Robert Wolkow

Position will remain open until fille.

All qualified candidates are encouraged to apply. We thank all applicants for their time and effort but only those selected for an interview will be contacted. Applicants may be considered for future vacancies.

COVID-19 Vaccination: Proof of full vaccination against COVID-19 in compliance with the University’s COVID-19 Vaccination Directive. Fully Vaccinated means a status an individual achieves 14 days after having received the recommended number of doses of a COVID-19 vaccine approved by Health Canada or the World Health Organization, and requires the individual to maintain the recommended number and type of vaccine doses as updated and required by Health Canada thereafter.

All qualified candidates are encouraged to apply; however, Canadians and permanent residents will be given priority. If suitable Canadian citizens or permanent residents cannot be found, other individuals will be considered. The University of Alberta is committed to an equitable, diverse, and inclusive workforce. We welcome applications from all qualified persons. We encourage women; First Nations, Métis and Inuit persons; members of visible minority groups; persons with disabilities; persons of any sexual orientation or gender identity and expression; and all those who may contribute to the further diversification of ideas and the University to apply.
