Separation of kinetic rate orders in extreme ultraviolet transient grating spectroscopy

Majed Chergui, Giulia Fulvia Mancini, Michele Puppin, Oliviero Cannelli, Camila Bacellar Cases Da Silveira, Serhii Polishchuk, Rebecca Ann Ingle, Hugo Jean Baptiste Marroux

We present an extreme ultraviolet (EUV) transient grating (TG) experiment of the spinel Co3O4 compound using tuneable incident energies across the Co M-2,M-3-edge and a 395 nm probe pulse, detecting both the first and the second diffraction orders (SDOs). ...

GeSn as next-generation material for short-wave infrared single-photon detection

Andrea Giunto

In recent years, the automotive industry has aspired to bring self-driving vehicles to the general public and light detection and ranging (LiDAR) sensors have emerged as the preferred solution for car vision systems. At present, LiDAR technologies employ e ...

Metasurface Near-Field Measurements with Incident Field Reconstruction Using a Single Horn Antenna

Shourya Dutta Gupta, Ville Tuovi Tiukuvaara

Metasurfaces (MSs) are the 2-D equivalent of metaterials, the latter being a class of artificial engineered materials exhibiting peculiar electromagnetic properties [1], [2]. Generally constructed as arrays of deeply sub-wavelength resonant particles on a ...

An Experimental Study Of The Photoresponse Of 1T-1R Oscillators Based On Vanadium Dioxide: Towards Spiking Sensing Systems

Olivier Martin, Mihai Adrian Ionescu, Teodor Rosca, Marco Riccardi, Fatemeh Qaderi Rahaqi

In this work we investigate the effect of visible light radiation on compact 1T-1R relaxation spiking oscillator cells based on 2-terminal Vanadium dioxide (VO2) structures. We illuminate the devices using a tunable wavelength laser between 400 and 850 nm ...

Graph-based regularization of inverse problems in imaging

Mattia Rossi

As of today, the extension of the human visual capabilities to machines remains both a cornerstone and an open challenge in the attempt to develop intelligent systems. On the one hand, the development of more and more sophisticated imaging devices, capable ...

Multi-Channel AlGaN/GaN In-Plane-Gate Field-Effect Transistors

Elison de Nazareth Matioli, Jun Ma, Catherine Erine, Giovanni Santoruvo

In this letter, we present a multi-channel in-plane-gate field effect transistor (MC-IPGFET). In the proposed device, multiple vertically stacked two-dimensional electron gases (2DEGs) are simultaneously controlled by lateral in-plane gates formed with the ...
