Microfabricated Heteroepitaxial Oxide Structures on Silicon for Bolometric Arrays

Kim J.H., Grishin A.M., KTH Royal Institue of Technology, SE

To realize high sensitive bolometer, new material with higher TCR value is needed including the low thermal mass : small pixel size and very thin thermally isolated membrane. Mixed-valent manganese, perovskite La0.67(Sr, Ca)0.33MnO3 (LSCMO) films [...]

A Nanocore/CMOS Hybrid System-on-Package (SoP) Architecture for Future Nanoelectronic Systems

Weerasekera R., Liu J., Zheng L-R, Tenhunen H., LECS/IMIT/KTH, SE

We propose Autonomous Error-Tolerant (AET) cellular network based architecture for future nano-electronic systems. Each AET cell consists of a nano-core, dedicated for local computing, CMOS cell-peripherals, responsible for cell I/O and System-level tasks, and their [...]

RuO2 and Ru Nanoparticles for MISiC-FET Gas Sensors

Salomonsson A., Roy S., Aulin C., Ojamäe L., Käll P.-O., Strand M., Sanati M., Lloyd Spetz A., IFM, SE

Catalytically active nanoparticles used as gate material on SiC-FET gas sensors. The goal is to improve the selsectivity and senstitivty.The sensors are sensitive towards oxidising and reducing gases (H2, NH3, C3H6).

Growth of Individual Vertically Aligned Nanotubes/Nanofibers with Small Diameter by PECVD on Different Metal Underlayers

Kabir M.S., Morjan R.E., Svensson K., Nerushev O.A., Lundgren P., Bengtsson S., Enokson P., Campbell E.E.B., Chalmers University of Technology, SE

The primary goal of this work is to achieve significant improvement of growth of carbon nanotubes (CNTs) on different metal underlayers that can provide a platform for electronic companies to adopt the technology into their [...]

Molecular Dynamics of Biomimetic Ionomers Studied by Dielectric Spectroscopy on the Nanometer Length Scale

Welch K., Nederberg F., Bowden T., Strømme M., Uppsala University, SE

New biomimetic materials are being developed which show great promise for biotechnological applications. An understanding of the dynamic molecular processes in these materials at the nanoscale level is of particular interest and we show that [...]

Electronic Nanotechnology Based on Non-Binary Principles

Mathew J., Dubrova E., Tenhunen H., Royal Institute of Technology, Stockholm, SE

This paper describes alternative to binary number representations and discuss possibilities for implementing multiple-valued functions using chemically assembled electronic nanotechnology. The implementation of a four-valued adder using molecular diodes is presented. The proposed structure is [...]

Conductance of a Disordered Double Quantum Wire in a Magnetic Field: Boundary roughness scattering

Arapan S.C., Korepov S.V., Liberman M.A., Johansson B., Uppsala University, SE

Boundary roughness scattering in disordered tunnel-coupled double quantum wires in the presence of a magnetic field is considered. The low-temperature conductance as a function of applied magnetic field is calculated for different structure and disorder [...]

Logic Optimization and Technology Mapping for CAEN

Färm P., Dubrova E., Tenhunen H., IMIT, KTH, SE

This paper considers the architectures and design issues involved in creating a nano-electronic computing system. We focus on the problems of technology dependent optimization and technology mapping for Chemically Assembled Electronic Nanotechnology (CAEN). We present [...]

Numerical Simulations of Flat-Walled Diffuser Elements for Valveless Micropumps

Olsson A., Stemme E., Stemme G., Stemme E., Stemme G., Royal Institute of Technology, SE

The flow directing capability of micromachined flat-walled diffuser elements for valve-less micropumps have been investigated. The diffuser element is a small angle flow channel with a rounded inlet and a preferably sharp outlet. The diverging-wall [...]

The Valveless Diffuser Pump-A Numerical Design Study Using MATLAB

Olsson A., Stemme E., Stemme G., Stemme E., Stemme G., Department of Signals, Sensors and Systems, SE

A lumped-mass model is used to improve the design of the valveless diffuser pump. The model is implemented using MATLAB and tested for different previously reported pumps. The flow-pressure characteristics are predicted for different excitation [...]
