Our group studies the electronic properties of molecular and mechanical systems at the nanoscale. Most of the experiments we perform involve a combination of top-down and bottom-up nanotechnology. Molecular electronics, semiconducting nanoparticles and room temperature nano-electromechnical systems. Mircowave probes of motion and matter. Quantum optics at the nanoscale.

In our lab we synthesize artificial crystals of complex materials layer by layer in order to create designer quantum matter such as two-dimensional systems of interacting electrons. After synthesis, we explore the electronic properties of our artificial materials by means of a variety of experimental probes, including electrical and thermal transport at the nanoscale, ultrafast dynamics, x-ray and optical spectroscopy. Our main focus is on a class of materials known as complex oxides.

Quantum optomechanics with photonic crystals. Group at Caltech and the Aspelmeyer. We also integrate the optical cavity into our mechanical systems by patterning a photonic crystal onto the devices, which is a periodic structure with a photonic bandgap at our laser frequency. The experiments themselves involve techniques from quantum optics, finite element simulation, cryogenics, RF and high-vacuum technology. Our paper on a method of characteri.

Mesoscopic superconductivity and quantum matter. Our research-group is fascinated by new states of matter. O ne such state is the ferromagnetic state, known for thousands of years in, for example, the compass. Another one is the superconducting state, which is known since 1911. The current nanotechnology makes it possible to combine those different ground states. 1985-1998 Professor University of Groningen. 1999-2013 Professor Delft University of Technology.

Welcome to the Steele Lab website in the MED group at the Department of Quantum Nanoscience. In the Kavli Institute of Nanoscience. At the Delft University of Technology. The core of our research is focussed on using microwave photons trapped in superconducting circuits to probe and control mechanical resonators in the quantum regime. For more information on who we are and the types of things we do, see the links in the menus above.

We study the physics of nanodevices with the goal to apply them in the semiconductor industry. Miniaturization of device dimensions towards the nanoscale can offer clear advantages in terms of operation speed, device density and sensitivity. CMOS integration of nanomaterials is therefore expected to enable breakthroughs in computing, communication and sensing. We keep close contacts with industrial scientists to benchmark our devices and assess their application potential.
