PhD position: dynamic nanophotonics with 2D quantum materials


Publication date 19 December 2019


Closing date 15 February 2020


Level of education Master's degree


Hours 38 hours per week


Salary indication €2,325 to € 2,972 gross per month

Are you a highly-motivated physicist with a strong affinity for nanotechnology and optoelectronic experiments? We are seeking an excellent and ambitious PhD candidate to perform fundamental research at the interface of nanophotonics and two-dimensional (2D) quantum materials.

 

Transition-metal dichalcogenides are semiconducting materials that are layered like a stack of paper in one dimension, bound only by van-der-Waals forces. In the monolayer limit, these 2D materials have a direct optical bandgap and show a very large exciton binding energy due to the lack of dielectric screening. As such, these materials are atomically-thin (less than 1 nm thick) and exhibit a very strong quantum-mechanical exciton resonance – even at room temperature. This exciton resonance is highly sensitive to external stimuli, including electric fields, dielectric surrounding, strain, and changes in carrier density. In this project, we will employ these external stimuli to gain control over the very strong light-matter interaction of the excitons, and manipulate the flow of light at the nanoscale.

 

First, we will study the solid-state physics of light interacting with exciton resonances exposed to external fields and charge densities at low temperatures. Second, we will use cleanroom-fabricated nanoscale devices to realize active control over light scattering by excitons in 2D semiconductors. Finally, we will leverage this active control over the excitonic light scattering to demonstrate dynamically-tunable nanophotonic devices. The results of this work could be used to develop a new class of atomically-thin optical coatings, in which we tune the optical functionality through manipulation of the exciton resonance.

 

What are you going to do?

You are expected to perform fundamental research on the understanding, control, and use of quantum mechanical exciton resonances in 2D semiconductors for the development of new dynamic nanophotonic devices.

You will:

  • fabricate nanopatterned optical coatings and nanoscale devices in the cleanroom of the AMOLF NanoLab Amsterdam;
  • design and construct experimental setups to perform optoelectronic measurements at low temperatures;
  • develop theory and computer simulations to support the experimental results;
  • present your results in national and international workshops/conferences;
  • collaborate with other research groups within the Quantum Matter and Nanophotonic Materials groups within the UvA, as well as groups within the VU, AMOLF, and international collaborators;
  • take part in the teaching effort of the group, including supervision of bachelor and master students.


What do we require?

  • A master’s degree in experimental physics, or a closely related discipline;
  • enthusiasm for collaborations and interdisciplinary research;
  • excellent written and oral communication skills in English.

Other skills, experiences, and documents that would benefit your application:

  • previous experience in an optical physics lab or cleanroom nanofabrication;
  • a background in material science of 2D materials;
  • demonstrated experience with programming language (matlab, python, labview);
  • scientific publications.

 

Our offer

A temporary contract for 38 hours per week, preferably starting as soon as possible for the duration of 4 years. The initial appointment will be for a period of 18 months. After a satisfactory evaluation it can be extended for a total duration of 4 years and should result into a PhD dissertation. We will draft an educational plan that includes attendance of courses and (international) meetings/conferences.

The salary, depending on relevant experience before the beginning of the employment contract, will be €2,325 to €2,972 (scale P) gross per month, based on fulltime (38 hours a week), excluding 8% holiday allowance and an 8.3% end-of-year bonus. A favorable tax agreement, the '30% rule', may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.
