A Defect Model for Metallic Carbon Nanotubes in Cell-based Logic Circuits

Hashempour H., Lombardi F., Northeastern University, US

Carbon Nanotube based Field Effect Transistors (CNTFET) are promising nano scaled devices for implementing high performance, highly integrated, and low power circuits. The main component of a CNTFET is a single-wall carbon nanotube (SWCNT); its [...]

Fluidic Nanoelectronics and Brownian Dyanmics

Lyshevski M.A., Lyshevski S.E., Lyshevski M.A., Lyshevski S.E., Microsystems and Nanotechnologies, US

The fundamentals of Brownian dynamics and it application are examined. In the development of mathematical model for Brownian particle motion, we integrate the asymmetric potential as well as consider stochastic electric, magnetic, hydrodynamic and thermal [...]

Crystalline Magnetotunnel Junctions: Fe-MgO-Fe, Fe-FeOMgO-Fe and Fe-AuMgOAu-Fe

Stilling M., Stokbro K., Flensberg K., Copenhagen University, DK

The dimension of electronic devices is rapidly scaling down, and the ratio between surface and bulk atoms therefore increasing. This has the consequence that the interfaces between different parts of the device start to have [...]

Reproducibility of Silicon Single Electron Quantum Dot Transistor

Hasim U., Sutikno S., Nothern Malaysia University College of Engineering, MY

In principle, based on the form of tunnel junction, single electron transistor (SET) can be classified into four types, i.e. nanowire SET, quantum dot SET, nanotube SET and point contact SET. Another classification is SET [...]

Magnetic switch induced electron transport in a double quantum dot

Popsueva V., Førre M., Hansen J.P., University of Bergen, NO

The paper presents a theoretical analysis of controlled singleelectron quantum transport in a two dimensional double quantumdot. The transport is induced by a time dependent magnetic field.From solving the time dependent Schrodinger equation we find [...]

Practical nanotechnology in Electronics

Hammer-Fritzinger D., NanoDynamics Inc., US

Nanotechnology has been hailed as the “next wave” to replace CMOS as the process of choice to make logic devices using technologies as diverse as carbon nanotube grids, polymer semiconductors and even “wetware” – ionic/electronic [...]

Inner Sidewall Gate MOSFET with HfO2 gate Dielectric and Pt electrode

Im K., Ahn C-G, Yang J.H., Baek I-B, Choi C-J, Lee S., Hwang H., Cho W-J, Choi C-J, Electronics and Telecommunications Research Institute, KR

UTB ISG MOSFET with gate length of 60 nm was fabricated with HfO2 gate dielectric and Pt gate electrode. The proposed device has some advantage over conventional replacement gate process. Besides simpler process, the remaining [...]

Effect of Fin Angle on Electrical Characteristics of Nanoscale Bulk FinFETs

Li Y., Chen W-H, National Chiao Tung University, TW

Bulk-finFET (fin-shaped field effect transistor) has been viewed as a good candidate for nanoscale VLSI device fabrication and nanoelectronic circuit design [1-5]. The structure features an excellent device characteristics compared with conventional planer structures. In [...]

Numerical Modelling of Experimentally Fabricated Inas/Gaas Quantum Rings

Filikhin I., Deyneka E., Vlahovic B., North Carolina Central University, US

In the presented work we apply a single subband model for InAs/GaAs QD(QR), where the electron effective mass depends on the confinement energy by the Kane formula. The geometrical parameters of the model are based [...]

Mobility of Electrons in Rectangular Si Nanowires

Ramayya E., Vasileska D., Goodnick S.M., Knezevic I., Arizona State University, US

We investigate two issues in this paper. First, we examine the role of interface-traps on the device drain current in an SOI nanowire MOSFET. Afterwords, we investigate the role of the interface-roughness on the low-field [...]
