Optical Spectroscopy of Nanostructured Materials lab
Aim and equipment
The capability of modifying the physical properties of elemental and compound semiconductors through deliberate incorporation of foreign atoms into the crystal has led to the birth of modern electronics and optoelectronics. Improved performance and multifunctionality of devices have paralleled the progress achieved in the synthesis and engineering of new materials and in the control and modification of their physical properties at nanometre scale lengths. In particular, the synthesis of nanostructured semiconductors is incessantly boosting the number of solutions and the degree of flexibility available for large integration processes in electronics and photonics.
In our group, we address the electronic properties of novel semiconductor materials and nanostructures by investigating the emission and absorption of light in these systems. This can be accomplished by the use of several instruments and devices that excite materials and analyse spectrally and spatially subsequent light emission/absorption.
The following research topics are presently studied in our group (please follow the links for more information): semiconducting nanowires, nanostructures and photonics, two-dimensional materials, and hydrogen in novel materials.
Next, the main instrumentation available in our group is shown and briefly described.

The members of the Optical Spectroscopy of Nanostructured Materials Laboratory have decades of experience in the optical characterization of semiconductor materials and nanostructures. The lab is equipped with state-of-the-art facilities for optical spectroscopy, including:
|
- Double (0.75 m) and single (0.16, 0.3, and 1 m) monochromators.
|
|
- Very recently we also designed and built a setup for photon correlation measurements (both pulsed and CW), which gave us the ability to fully characterize the performance of the investigated nanostructures as single- and entangled-photon emitters.
