Dynamic nuclear polarization by frequency modulation of a tunable gyrotron of 260 GHz

Stefano Alberti, Jean-Philippe Ansermet, Falk Hans Braunmüller, Philippe Cuanillon, Murari Soundararajan, Dongyoung Yoon

An increase in Dynamic Nuclear Polarization (DNP) signal intensity is obtained with a tunable gyrotronproducing frequency modulation around 260 GHz at power levels less than 1W. The sweep rate of frequency modulation can reach 14 kHz, and its amplitude is ...

Versatile High Repetition Rate 2-μm Pulsed Source Based on Wideband Parametric Conversion

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report an all-fiber pulsed source based on parametric conversion followed by thulium amplification able to deliver picosecond pulses at a repetition rate selectable between 2 and 5 GHz, of which central wavelength can be freely selected in the 2-μm regi ...

Inverted Current-Voltage Hysteresis in Mixed Perovskite Solar Cells: Polarization, Energy Barriers, and Defect Recombination

Michael Graetzel, Wolfgang Richard Tress, Michael Saliba, Antonio Abate

Organic-inorganic metal halide perovskite solar cells show hysteresis in their current-voltage curve measured at a certain voltage sweep rate. Coinciding with a slow transient current response, the hysteresis is attributed to a slow voltage-driven (ionic) ...

A Switched Oscillator Geometry Inspired by a Curvilinear Space-Part I: DC Considerations

We present a new technique for the design and test of coaxial switched oscillators (SWOs). In this paper (Part I of a two-part paper), we concentrate on the electrostatic design of coaxial SWOs. We introduce a new design for the electrodes, which have been ...

Full-wavefield modeling and reverse time migration of laser ultrasound data: A feasibility study

Thomas Emmanuel Blum

Laser ultrasound (LU) data acquired on cylindrical core samples effectively probe the physical properties of geologic materials. Although most LU analyses focus on estimating and inverting traveltimes of direct arrivals, it is important to recognize that L ...

Comparison of two optimized readout chains for low light CIS

Christian Enz, Assim Boukhayma

We compare the noise performance of two optimized readout chains that are based on 4T pixels and featuring the same bandwidth of 265kHz (enough to read 1Megapixel with 50frame/s). Both chains contain a 4T pixel, a column amplifier and a single slope analog ...
