A continuous-wave and pulsed X-band electron spin resonance spectrometer operating in ultra-high vacuum for the study of low dimensional spin ensembles

Giovanni Boero, Fabio Donati, Soyoung Oh

We report the development of a continuous-wave and pulsed X-band electron spin resonance (ESR) spectrometer for the study of spins on ordered surfaces down to cryogenic temperatures. The spectrometer operates in ultra-high vacuum and utilizes a half-wavele ...

FEM simulation: Thermal properties of thin film quartz and silicon resonators

This semester project aimed at simulating two approaches for low temperature dependence of resonance frequency of resonators. The first one consists in using AT-cut quartz as the resonator’s material. The AT-cut quartz wafers are made using a 35° angle wit ...

Transient Electronics for Smart Biodegradable Medical Implants

Matthieu Jean Michel Rüegg

Bioresorbable implantable medical devices show great potential for applications requiring medical care over well-defined periods of time. Such implants naturally degrade and resorb in the body, which eliminates adverse long-term effects or the need for a s ...

Spin-dependent charge transfer at chiral electrodes probed by magnetic resonance

Jean-Philippe Ansermet, Christophe Roussel, Felix Blumenschein, Mika Antero Tamski

Chirality-induced spin selectivity is evidenced by exciting the spin resonance of radicals in an electrochemical cell where the working electrode is covered with a chiral self-assembled monolayer. Because the electron transfer to and from the paramagnetic ...

ROYAL SOC CHEMISTRY2020

We will discuss our recent experimental progress on developing active acoustic resonators that provide in- dependently tunable acoustic properties, namely the possibility to control at will their resonance frequency, absorption losses, and radiative losses ...

Analysis of XBAR resonance and higher order spurious modes

Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky

A suspended 400nm thin mono-crystalline ZY cut Lithium Niobate (LN) membrane with narrow interdigital electrodes (IDEs) on top having a pitch of the order of few microns excites standing shear bulk acoustic wave resonance (XBAR) within the membrane through ...

Laterally excited bulk wave resonators (XBARs) based on thin Lithium Niobate platelet for 5GHz and 13 GHz filters

Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Soumya Yandrapalli, Victor Plessky, Muhammad Faizan

In a free ZY-LiNbO3 400nm thick platelet, narrow electrodes (500nm wide) placed periodically with a pitch of few micrometers can eXcite standing Bulk Acoustic shear wave Resonances (XBARs), by means of lateral electric field parallel to crystalline Y- axis ...
