Superconducting microwave oscillators as detectors for ESR spectroscopy

Jürgen Brugger, Giovanni Boero, Yu Rao, Reza Farsi

Microwave superconducting resonators are extensively studied in fields such as quantum computing and electron spin resonance (ESR) spectroscopy. However, the integration of superconducting resonators with feedback mechanisms to create ultra-low noise oscil ...

Deterministic grayscale nanotopography to engineer mobilities in strained MoS2 FETs

Jürgen Brugger, Nicola Marzari, Andras Kis, Giovanni Boero, Georg Fantner, Xia Liu, Marcos Penedo Garcia, Norma Rivano, Jin Jiang, Berke Erbas

Field-effect transistors (FETs) based on two-dimensional materials (2DMs) with atomically thin channels have emerged as a promising platform for beyond-silicon electronics. However, low carrier mobility in 2DM transistors driven by phonon scattering remain ...

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 ...

200 GHz single chip microsystems for dynamic nuclear polarization enhanced NMR spectroscopy

Giovanni Boero, Nergiz Sahin Solmaz, Reza Farsi

Dynamic nuclear polarization (DNP) is one of the most powerful and versatile hyperpolarization methods to enhance nuclear magnetic resonance (NMR) signals. A major drawback of DNP is the cost and complexity of the required microwave hardware, especially at ...

Laser-Induced Forward Transfer of SU-8 Microdisks as Carriers of Metallic Microdevices

Jürgen Brugger, Giovanni Boero, Zhiwei Yang

Laser-induced forward transfer (LIFT) is a digital additive manufacturing technique that uses a pulsed laser to transfer various materials from a donor film to a receiver substrate placed in close proximity. In this work, we investigate the transfer of SU- ...

Combining thermal scanning probe lithography and dry etching for grayscale nanopattern amplification

Jürgen Brugger, Andras Kis, Giovanni Boero, Georg Fantner, Arnaud Bertsch, Xia Liu, Marcos Penedo Garcia, Berke Erbas, Mitali Banerjee, Ana Conde Rubio

Grayscale structured surfaces with nanometer-scale features are used in a growing number of applications in optics and fluidics. Thermal scanning probe lithography achieves a lateral resolution below 10 nm and a vertical resolution below 1 nm, but its maxi ...

Element-specific X-Ray detection of electron paramagnetic resonance in thin films of quantum bits

Harald Brune, Giovanni Boero, Stefano Rusponi

Element-specific magnetism accessible by synchrotron-based X-ray spectroscopy has proven to be valuable to study spin and orbital moments of transition metals and lanthanides in technologically relevant thin-film and monolayer samples. The access to cohere ...

500 MHz high resolution proximity sensors with fully integrated digital counter

Giovanni Boero, Nergiz Sahin Solmaz, Reza Farsi

We report on the design and characterization of two inductive proximity sensors based on LC oscillators operating at 500 MHz. The distance from the target is obtained by measuring the oscillation frequency variation. Both sensors contain an off-chip LC res ...

Towards optical MAS magnetic resonance using optical traps

Giovanni Boero, Nergiz Sahin Solmaz, Reza Farsi, Jens Anders

Higher magic angle spinning (MAS) frequencies than currently available are desirable to improve spectral resolution in NMR and EPR systems. While conventional strategies employ pneumatic spinning limited by fluid dynamics, this paper demonstrates the devel ...
