LAB and RESEARCH
NanoFacility Piemonte is part of the QR INRiM laboratory complex where particle control chamber is available in ISO class 5 and ISO class 7.
This facility allows the realization of micro- and nanoscale materials and devices through electron beam lithography, focused ion beam sculpturing, optical lithography. Also, in these laboratories several systems are operative for deposition and chemical etching of metallic, insulating and magnetic thin films.
Electrical Resistance Tomography
Electrical resistance tomography (ERT) is a way to perform traceable and spatially resolved electrical measurements of thin films and 2D materials.
This technique retrieves a map of the electrical conductivity of the interior of the sample from a set of four-terminal resistance measurements performed at its boundary.
It can be easily implemented without lithographic steps.
First ERT map of a graphene was achieved at INRIM in 2019.
Electrical noise analyzer
The electrical noise analyzer developed at INRIM is based on cross-correlation, which rejects to a large extent the noise of the amplifiers, and thus allows to determine the device noise power spectrum under DC current excitation.
Our cross-correlation analyzer is based on a two-channel voltage signal conditioning system, including low-noise, high-gain amplifiers and a synchronous sampling system. The acquired samples are processed by a digital correlation algorithm.
