Photonics and Semiconductor Nanophysics

Photonics and Semiconductor Nanophysics

The Applied Physics research group Photonics and Semiconductor Nanophysics uses the NanoLab facilities


  • To grow III/V based systems for studies on the relation between the structural properties, such as size, shape and composition, and their opto-electronic and magnetic properties.
  • To grow nanowires for fundamental studies, and for use in solar cells and thermo electrics
  • To fabricate nanophotonic devices, including quantum dot light emitters, tuneable photonic crystal cavities, and superconducting single-photon detectors.

 

MBE

The group uses two molecular beam epitaxy (MBE) machines for the growth of InGaAs-based systems, such as quantum dots..

MOVPE

In addition, the group uses metalorganic vapor phase epitaxy (MOVPE) machines for device applications of quantum dots emitting in the 1.55 ┬Ám telecom wavelength region such as lasers and optical amplifiers, as well as their implementation in integrated photonic circuits

The close-coupled showerhead MOVPE is used for the growth of nanowires. A variety of group III (Al, Ga, and In), group V (P, As, and Sb), and impurity dopants (Si, Si, Zn, Fe) are available. Research is focused on exploring the optical and electrical properties of nanowires by tuning their crystal structure, dimensions, composition and lattice strain. This reactor is used as the National Nanowire Growth Facility.  Academic groups in the Netherlands can request for materials or collaborations (ebakkers@tue.nl).
