Photoluminescence characterization of few-nanocrystals electronic devices

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Photoluminescence (PL) spectroscopy is demonstrated as a suitable technique to characterize silicon nanocrystals (Si-NCs)-based nonvolatile memory devices. The 2D array of Si-NCs forming the floating gate is obtained by low-energy ion implantation in thin ...

Ferroelectric gate for control of transport properties of two-dimensional electron gas at AlGaN/GaN heterostructures

Nava Setter, Paul Muralt, Igor Stolichnov, Lisa Malin

The concept of a field-effect transistor with ferroelectric gate has been implemented using the GaN/AlGaN heterostructure combined with Pb(Zr,Ti)O-3 ferroelectric layer. The processing conditions were optimized in a way to obtain textured Pb(Zr,Ti)O-3 film ...

Internet-scale storage systems under churn - A study of the steady state using Markov models

Karl Aberer, Anwitaman Datta

Content storage in a distributed collaborative environment uses redundancy for better resilience and thus provides good availability and durability. In a peer-to-peer environment, where peers continuously leave and rejoin the network, various lazy strategi ...

Microscopic aspects of the region-by-region polarization reversal kinetics of polycrystalline ferroelectric Pb(Zr,Ti)O-3 films

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla, Lisa Malin

The region-by-region polarization switching in ferroelectric Pb(Zr,Ti)O-3 thin films sandwiched between Pt electrodes has been directly observed using piezoelectric scanning probe microscopy. A resolution improved by one order-of-magnitude compared to the ...

Integration and modeling of ferroelectric devices in a standard CMOS porcess for low power non-volatile memories

Vincent Meyer

The present work analyzes the impact of ferroelectric materials like PZT when integrated in a standard 0.5µm CMOS process in order to realize nonvolatile memories. The project has been initiated conjointly by the Swiss Federal Institute of Technology of La ...

Internet-scale storage systems under churn - A steady state analysis

Karl Aberer, Anwitaman Datta

Content storage in a distributed collaborative environment uses redundancy for better resilience. This redundancy is either achieved by pure replication or using erasure codes for more efficient utilization of available storage. Increasingly such schemes a ...

High-density electrode array for imaging in vitro electrophysical activity

Nico de Rooij, Peter Van der Wal

The development of a high-density active microelectrode array for in vitro electrophysiology is reported. Based on the Active Pixel Sensor (APS) concept, the array integrates 4096 gold microelectrodes (electrode separation 20 μm) on a surface of 2.5 mm x 2 ...

Nature of nonlinear imprint in ferroelectric films and long-term prediction of polarization loss in ferroelectric memories

Nava Setter, Alexander Tagantsev, Igor Stolichnov

The phenomenon of polarization imprint consisting of the development of a preferential polarization state in ferroelectric films is known as one of the major issues impacting the development of high density ferroelectric memories. According to the commonly ...

GosSkip: a Gossip-based Structured Overlay Network for Efficient Content-based Filtering

Rachid Guerraoui, Anne-Marie Kermarrec, Sidath Handurukande

It is appealing to implement publish/subscribe systems in a peer to peer (P2P) manner to circumvent the scalability issues of broker-based (semi-decentralized) systems and simplify the deployment. While existing P2P generic infrastructures provide a scalab ...
