A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Serguei Okhonin, Adil Koukab, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...

Simultaneous High-Speed High-Resolution Nanomechanical Mass Sensing

Maher Kayal, Marc Pastre, Christian Kauth

Mass sensing has so far rather developed along the resolution axis, reaching atomic-scale detection, than into the direction of high speed. This letter reports on a novel self-calibrating technique that makes high-speed inertial mass sensors capable of ins ...

System-Level Design Considerations for Carbon Nanotube Electromechanical Resonators

Maher Kayal, Jean-Michel Sallese, Marc Pastre, Christian Kauth

Despite an evermore complete plethora of complex domain-specific semiempirical models, no succinct recipe for large-scale carbon nanotube electromechanical systems design has been formulated. To combine the benefits of these highly sensitive miniaturized m ...
