Review of Ge(GeSn) and InGaAs Avalanche Diodes Operating in the SWIR Spectral Region

open access: yesNanomaterials, 2023
Among photodetectors, avalanche photodiodes (APDs) have an important place due to their excellent sensitivity to light. APDs transform photons into electrons and then multiply the electrons, leading to an amplified photocurrent.

Combinatorial hybrid systems [PDF]

open access: yes2008 IEEE International Conference on Computer-Aided Control Systems, 2008
As initially suggested by E. Sontag, it is possible to approximate an arbitrary nonlinear system by a set of piecewise linear systems. In this work we concentrate on how to control a system given by a set of piecewise linear systems defined on simplices. By using the results of L. Habets and J.
