What We Can Learn about Business Modeling from Homeostasis

Business modeling methods most often model an organization’s value provision to its customers followed by the necessary activities and structure to deliver this value. These activities and structure are seen as infinitely malleable; they can be specified a ...

Ultralow Leakage Current AlGaN/GaN Schottky Diodes With 3-D Anode Structure

Elison de Nazareth Matioli, Bin Lu

We demonstrate ultralow leakage current AlGaN/GaN Schottky-barrier diodes (SBDs) based on a 3-D anode contact. In contrast to conventional AlGaN/GaN SBDs, this new device forms a Schottky contact directly to the 2-D electron gas (2-DEG) at the sidewalls of ...

Platinum TSVs for High-Temperature Processing and Operation of Microsystems

Nico de Rooij, Danick Briand, Terunobu Akiyama, Rokhaya Gueye

We report on the fabrication and characterization of high-temperature Pt-TSVs. A LPCVD silicon nitride passivation layer was implemented to protect the TSVs from oxidation during high-temperature treatments and wet HF-based post-processing steps, the later ...

Detecting particles flowing through interdigitated 3D microelectrodes

Carlotta Guiducci, Enrico Accastelli, Samuel Kilchenmann, Elena Bianchi, Enrica Rollo

Counting cells in a large microchannel remains challenging and is particularly critical for in vitro assays, such as cell adhesion assays. This paper addresses this issue, by presenting the development of interdigitated three-dimensional electrodes, which ...

Flexible polyimide-based force sensor

Martinus Gijs, Jagoda Anna Dobrzynska

We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...

Observing the drop of resistance in the flow of a superfluid Fermi gas

Jean-Philippe Brantut

The ability of particles to flow with very low resistance is characteristic of superfluid and superconducting states, leading to their discovery in the past century. Although measuring the particle flow in liquid helium or superconducting materials is esse ...

Dynamical Coulomb Blockade Observed in Nanosized Electrical Contacts

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Electrical contacts between nanoengineered systems are expected to constitute the basic building blocks of future nanoscale electronics. However, the accurate characterization and understanding of electrical contacts at the nanoscale is an experimentally c ...

Investigation of the Electromechanical Properties of Graphene

Mohamed Malik Benameur

This thesis studies the optical and electro-mechanical properties of novel atomically thin crystals. It deals with the carbon based material, graphene, and with layered transition metal dichalcogenides with the common formula MX2. The first part describes ...

Nanosized Optoelectronic Devices Based on Photoactivated Proteins

Giovanni De Micheli, Sandro Carrara, Danilo Demarchi, Gianluca Piccinini

Molecular nanoelectronics is attracting much attention, because of the possibility to add functionalities to silicon-based electronics by means of intrinsically nanoscale biological or organic materials. The contact point between active molecules and elect ...

Conduction of Ultracold Fermions Through a Mesoscopic Channel

Jean-Philippe Brantut

In a mesoscopic conductor, electric resistance is detected even if the device is defect-free. We engineered and studied a cold-atom analog of a mesoscopic conductor. It consists of a narrow channel connecting two macroscopic reservoirs of fermions that can ...
