Electrical impedance spectroscopy - Dual lockin custom setup

The system was developed in house and is built around a dual lockin setup.

It is capable of measuring:

  • Frequency range: 1mHZ - 4 MHz
  • Stimuli Voltage range: nVolts - Volts
  • Response voltage range: nVolts - Volts
  • Current response range: pA - mA

The system can also operate in conjuction with the RF_VNA to cover a range of 9 orders of magnitude in frequency

Measurement can be:

Exploratory Science Lab - ISO7 clean room

The lab was recently (2015) launched to cover the needs of the activity. The clean room ensures stable Temperature / Humididty environment and is separated in three zones:

Zone 1: General processing

The main target if this zone is to enable hands on access to students (starting from undergraduate) to perform hand on work using basic equipment. This zone is equped with a solvent wet bench, spin coating and hotplates, optical microscopy and profilometry.

Zone 2: RF Characterization

Prof. Miguel Iván Alonso

06/2015 – 10/2016 Postdoc on BEC 2


During his postdoc on Crete he worked on the stability of BEC and its phase fluctuations as well as the “Q-factor”.

Before joining us, Ivan did his MsC in Instrumentation in Physics followed by his PhD at the Applied Physics Department of the University of Salamanca and the University of Salamanca. During this period he worked on the Equilibrium Thermodynamic characterization of liquids, liquid mixtures, the microscopic interpretation of the data via well-known statistical models based on the Guggenheim (quasi-Ising) lattice model, Flory equation of state and contribution group methods like DISQUAC and UNIFAC.

After doing a postdoc at the University of BurgosIvan is now a  Professor at the Universitat de les Illes Balears.
