GeSn as next-generation material for short-wave infrared single-photon detection

In recent years, the automotive industry has aspired to bring self-driving vehicles to the generalpublic and light detection and ranging (LiDAR) sensors have emerged as the preferred solution forcar vision systems. At present, LiDAR technologies employ exp ...

Toward the Super Temporal Resolution Image Sensor with a Germanium Photodiode for Visible Light

Edoardo Charbon

The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is 11.1 ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material ...

The CERN accelerators deliver a wide spectrum of secondary beams to the Experimental Areas. These beams are composed of hadrons, leptons, and heavy ions that can vary greatly in momentum (1 GeV/c to 400 GeV/c) and intensity (10^2 to 10^8 particles per seco ...

Development of the scintillating fibre tracker technology for the LHCb upgrade and the LHC beam profile monitoring system

Olivier Göran Girard

The LHCb detector located at the large hadron collider (LHC) at CERN will undergo a major upgrade in 2019-2020. The detector will be prepared to operate at an increased instantaneous luminosity and to read out full events at 40MHz. This requires many chang ...

Photodiode Response in a CH3NH3PbI3/CH3NH3SnI3 Heterojunction

László Forró, Endre Horvath, Bálint Náfrádi, Andrea Pisoni, Massimo Spina, Karoly Holczer

Here we report another surprising feature of the methylammonium metal halide material family, the phototunability of the diode response of a heterojunction made of CH3NH3PbI3 and its close relative, CH3NH3SnI3. In the dark state the device behaves as a dio ...

CMOS-Compatible PureGaB Ge-on-Si APD Pixel Arrays

Edoardo Charbon, Mahdi Aminian

Pure gallium and pure boron (PureGaB) Ge-on-Si photodiodes were fabricated in a CMOS compatible process and operated in linear and avalanche mode. Three different pixel geometries with very different area-to-perimeter ratios were investigated in linear arr ...

A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Adil Koukab, Serguei Okhonin, 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 ...

A comparative experimental investigation on responsivity and response speed of photo-diode and photo-BJT structures integrated in a low-cost standard CMOS process

Alexandre Schmid, Yusuf Leblebici, Nikola Katic

A variety of smart imaging and neuromorphic applications perform time-domain image acquisition in order to imitate biological systems and reduce the growing transmission bandwidth of the modern imaging devices. Because they operate in time-domain, they req ...
