Increased Photoconductivity Lifetimes in GaAs Nanowires via n-Type and p-Type Shell Doping

Anna Fontcuberta i Morral, Federico Matteini, Francesca Amaduzzi

Reliable doping in GaAs nanowires is essential for the development of novel optoelectronic devices. Previously, GaAs nanowires have been shown to exhibit extremely short photoconductivity lifetimes of a few picoseconds due to their high surface recombinati ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang, Jie Bian

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...

Photon-Counting Arrays for Time-Resolved Imaging

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Samuel Burri

The paper presents a camera comprising 512 x 128 pixels capable of single-photon detection and gating with a maximum frame rate of 156 kfps. The photon capture is performed through a gated single-photon avalanche diode that generates a digital pulse upon p ...
