Deep-UV-Enhanced Approach for Low-Temperature Solution Processing of IZO Transistors with High-k AlOx/YAlOx Dielectric

Danick Briand, Jaemin Kim, Alessio Mancinelli

Solution processing is an attractive alternative to standard vacuum fabrication techniques for the large-area manufacturing of metal oxide (MOx)-based electron devices. Here, we report on thin-film transistors (TFTs) based on a solution-processed indium zi ...

Simulation of CMOS APS Operation and Crosstalk in SPICE With Generalized Devices

Jean-Michel Sallese, Chiara Rossi

We present SPICE simulations of a CMOS APS pixel element consisting of the optical sensor with the sensing circuit. The photodiode is simulated at the physics level by means of the so-called Generalized Devices, without any predefined compact model. Conver ...

Electrochemical and morphological engineering of 2D materials for nanopore sensing

Martina Lihter

Nanopores are nanometer-sized holes that were initially proposed for DNA sequencing. Several years ago sequencing was made possible with biological nanopores. However, solid-state nanopores have plenty of advantages to offer compared to their biological co ...

On the Mechanistic Understanding of Photovoltage Loss in Iron Pyrite Solar Cells

Ulf Anders Hagfeldt

Considering the natural abundance, the optoelectronic properties, and the electricity production cost, iron pyrite (FeS2) has a strong appeal as a solar cell material. The maximum conversion efficiency of FeS2 solar cells demonstrated to date, however, is ...

Mahan excitons in room-temperature methylammonium lead bromide perovskites

Majed Chergui, László Forró, Endre Horvath, Ana Akrap, Edoardo Baldini, Márton Kollár, Tania Palmieri

In a seminal paper, Mahan predicted that excitonic bound states can still exist in a semiconductor at electron-hole densities above the insulator-to-metal Mott transition. However, no clear evidence for this exotic quasiparticle, dubbed Mahan exciton, exis ...
