Effect of metal/semiconductor interface on the resistance of a nonalloyed p-GaN/Ni–Au contact

Jules Duraz, Hassen Souissi, Maksym Gromovyi, David Troadec, Téo Baptiste, Géraldine Hallais, Nathaniel Findling, Phuong Vuong, Rajat Gujrati, Thi May Tran, Jean-Paul Salvestrini, Maria Tchernycheva, Suresh Sundaram, Abdallah Ougazzaden, Gilles Patriarche, Sophie Bouchoule

The formation of an ohmic p-contact represents a critical step in the processing of GaN-based devices such as light-emitting diodes (LEDs). Thermal annealing in an O2-containing atmosphere at high temperature of a GaN/Ni–Au contact is mostly used today, while nonannealed contacts have been reported...

Chamfer-engineered microcantilever probes for controlled electrical contact formation

Steve Arscott

<div><p>In miniature silicon-based microcantilever probes used for high-frequency on-wafer electrical measurements, microfabrication processes such as etching can produce sharp probe-tip edges and poorly controlled contacting geometries. During electrical contact formation, such...

Visible-Light-Driven Porphyrin/ZnO Nanohybrids for Ultrasensitive Room-Temperature Triethylamine Sensing

van Duy Lai, Thi Nguyet To, Valerio Allegra, Roberto Paolesse, Gabriele Magna, Franco Biasioli, Matteo Tonezzer, Alexandro Catini, Corrado Di Natale

Abstract Real-time monitoring of toxic triethylamine (TEA) at room temperature remains a significant challenge for metal oxide chemiresistors due to their typically high-power consumption and thermal requirements. This work presents a highly responsive, visible-light-activated gas sensor based on...

Nanoscale capacitive tuning of three dimensional terahertz meta-atoms

Usama Iqbal, Dmytro B. But, Théo Hannotte, Peretti Romain, Alexis Jouan, Cheryl Feuillet-Palma, Yanko Todorov

We report terahertz (THz) meta-atom resonators whose resonance can be tuned solely by varying the geometry of nanoscale capacitive elements while keeping the geometry of the inductive loop fixed. The capacitive parts employ a metal–dielectric–metal architecture with subwavelength dimensions,...

Vibrational transportation of deformable axisymmetric particles

Marina Terzi, Vladislav Aleshin, Jules Ghesquiere, Vincent Tournat

A particle on a substrate supporting a surface acoustic wave can experience horizontal drift excited by the dry friction force. The effect is referred to as vibrational transportation, or as a surface acoustic wave motor, and is used in a number of industrial applications. A traditional theory of...
