The Electroluminescence Laboratory allows the electro-optical characterization of micro/nano-electronic devices. Two darkened probe stations, resting on optical tables, are available. One is connected to a semiconductor parameter analyzer and a precision LCR meter, which make it possible to perform electrical tasks such as current-voltage, capacitance-voltage, capacitance-frequency and impedance spectroscopy measurements. The other one is equipped with another semiconductor parameter analyzer, two multichannel scalers, an arbitrary function generator, a digital oscilloscope and a grating monochromator coupled with two nitrogen cooled CCD cameras in the visible and infrared spectral range. This probe station is also equipped with two single photon detection modules, one based on a silicon APD for the visible range, the other based on a InGaAs/InP APD for the near infrared range. The measurements being collected with this setup are electroluminescence spectra (both in DC and AC regime), light emission intesity and time-resolved electroluminescence with resolution of 5 ns.
All the instruments can be controlled by dedicated LabVIEW softwares, which allow for semi-automatic measuring sessions.

These laboratories are equipped with all the instruments needed to perform chemical synthesis and functionalization reactions. The Laboratories have several chemical hoods (also to perform reactions in controlled atmosphere), benches and all the labware required to perform general chemical reactions. Synthesis of semiconductors and metallic nanoparticles, as well as their surface functionalization, are routinely performed.
Three spectrometers -covering from the UV to the IR spectral range- and a solar simulator to test photocatalytic activity are also available.

The laboratory is equipped with and Atomic Force Microscope (AFM), a Scanning Near Field Microscope (SNOM) and a homemade Scanning Ion Conductance Microscope (SICM) is under development.
The laboratory can perform a wide type of analysis. The AFM is able to perform the most common types of measurements (In air: STM/ STS/ Contact AFM/ LFM/Semicontact AFM/Noncontact AFM/ Phase Imaging/ Force Modulation mode/ Spreading Resistance Imaging/ MFM/ EFM/ SCM/ SKM/ Adhesion Force Imaging/ Shear force/ AFM (Force + Voltage) Lithography, STM Lithography, RM Lithography). The SNOM apparatus share the same controller of the AFM.
The SICM setup will be optimize to perform nanofluidics experiments on inorganic materials as well as the typical measurements on cells and biological material. The instrument has a dynamic range that further exceed the one of commercial apparatus, thanks to an homemade developed electronics that allows to achieve pA current resolution at µs time resolution, and a bias range of up to 40V at mV resolution.
An inverted microscope is also owned, together with two detection systems: a photon counting system (with ns time resolution) coupled with a 0.5 focal length monochromator for the vis-NIR range and a USB monochromator for the VIS range coupled to a CCD with us time resolution. A FemtoJet dispenser is also available.

In the Electrochemical Lab, we perform etching of materials by means of electrochemical reactions. The laboratory is equipped with two chemical hoods and two independent etching setups. I-V parameters are defined via software so that the complex patterns required for the Porous Silicon multilayers structures can be generated.
A spin coater and a stirred thermostated bath are also installed within this lab.
A nanofluidic setup is mounted on a designated station to characterize the diffusion properties of the fabricated (nano- to macro-) porous materials.

The aim of the Biosensing Lab is the application of silicon photonics as sensors for biological analysis. The general concept of such devices consist in an array of active sites functionalized with bioreceptors (DNA-aptamers or antibodies) to provide specific signals to detect the presence of the target analyte.

The lab is ready both for the labeled and label-free detection approach. In the first case we can collect the fluorescent signal of marked analyte either through integrated waveguides or through a CMOS photodetector array. In the second case, the analyte signal is obtained in real-time through the transmission spectra of dedicated photonic elements such as ring-resonators or Mach-Zehnder interferometers.

A dedicated fluidic handling setup is available, which can dispense volumes as low as 1 microliter with flow rates as low as 5 nanoliter per minute.

waveguidelab nanoscience UNITNWaveguide Lab is dedicated to the characterization of light-wave circuits. Two distinct setups allows for a broad range of linear and non-linear characterization and analysis. The light sources, detectors, signal transport and conditioning are based mainly on fiber optics, operating in the third telecom window. Light is injected and collected employing either butt-coupling or grating-based vertical-coupling techniques. Examples of the samples characterized are Whispery Gallery Mode (WGM) resonators coupled vertically to bus waveguides, Coupled-Resonator Optical Waveguides (CROWs) and Side-Coupled Integrated Spaced Sequence of Optical Resonators (SCISSORs). The measurements performed in the lab ranges from simple transmittance experiments to pump and probe time-resolved non-linear characterization. Examples of effects characterized are: four wave mixing (FWM) in waveguides, optomechanical response of vertically resonators coupled to bus waveguides, optical bistabilities and cahotic dynamics of resonator sequences.
