Quantum Dot Gate InGaAs FETs

Jain F., Suarez E., Gogna M., Chan P-Y., Karmakar S., Fikiet J., Miller B., Heller E., University of Connecticut, US

This paper describes using wide energy gap lattice-matched II-VI layers, such as ZnSeTe- ZnMgSeTe, serving as a high-k gate dielectric for n-channel enhancement mode InGaAs field effect transistors (FETs). The thrust is to reduce interface [...]

Plasmonic Enhancement in InGaN/GaN MQW System with Au Nanoparticles

Llopis A., Lin J., Neogi A., Pereira S.M.S., University of North Texas, US

In this article we report experimental evidence of plasmon based enhancement of an InGaN/GaN MQW system using Au nanocrystals. Enhancement of the main peak along with a blue-shift and change in the angle dependent PL [...]

Detailed Analysis of Quantum-Effects in Nanowire Tunneling Transistors with Different Channel-Profiles

Heigl A., Wachutka G., TU Munich, DE

Combining the operational principle of the tunneling field effect transistor with the idea of a multigate channel control appears as an attractive option to avoid unwanted shortchannel effects in nanometer-scale MOS-devices. This motivated us to [...]

Process- and Random-Dopant-Induced Characteristic Variability of SRAM with nano-CMOS and Bulk FinFET Devices

Li T-Y, Li Y., Hwang C-H, Li T-Y, Li Y., National Chiao Tung University, TW

The magnitude of the intrinsic parameter fluctuations, such as process-variation and random dopant fluctuation, steadily increase with the reduction of device dimensions, and lead to pronounced component mismatch in area constrained circuits such as static [...]

Castellated-Gate MOSFETs as Power Transistors for Nanometer CMOS and Post-CMOS Integrated Nanosystems

Seliskar J.J., HiperSem Inc., US

Analysis of the constant-voltage scaling characteristics of Fully-Depleted Castellated Gate (FDCG) MOSFETs reveals near term opportunities for these devices as the replacement for the “thick oxide” I/O device in CMOS System-On-A-Chip (SoC) technologies (e.g. the [...]

The INGAAS/GAAS Quantum Dots Under Effective and Ab Initio Treatments: Comparison and Results

Filikhin I., Suslov V.M., Vlahovic B., North Carolina Central University, US

An effective approach for describing the electronic structure of InGaAs/GaAs quantum dots (QDs) is presented. We model QDs based on a single sub-band approach with an energy dependent electron effective mass. The model assumes that [...]

Highly selective sensing of DMMP and NH3 using CNTFET array based gas sensors obtained using Spray-gun technique and fabricated with different metal electrodes to achieve gas electronic fingerprinting

Bondavalli P., Legagneux P., Pribat D., Gorintin L., Thales Research and Technology, FR

This paper deals with the prove of concept of an highly selective gas sensor based on CNTFETs which exploits the extremely sensitive change of the Schottky barrier heights between SWCNTs and metal electrodes. Specifically, the [...]

Enhanced UV Light Emission in Silicon nanoparticles

Singh A., Grycznski K.G., Rout B., Li J., McDaniel F., Neogi A., Sahu G., Mahapatra D.P., University of North Texas, US

UV light emission comparable to GaN based semiconductor is observed from gold-implanted Si (100) semiconductors. A low energy Au implant forming the Si nanoparticles or quantum dots are been irradiated and recrystallized by a MeV [...]

The Patterning of Sub-500 nm Inorganic Structures for Hybrid Photovoltaics

Hampton M.J., Williams S.S., Retterer S.T., Templeton J.L., Samulski E.T., DeSimone J.M., The University of North Carolina at Chapel Hill, US

The Pattern Replication In Non-wetting Templates (PRINT) technique has been extended to patterning of isolated features as well as embossed films of sub-500 nm “hard” inorganic oxides and nanocrystalline semiconductors including TiO2, SnO2, ZnO, ITO, [...]

Water Soluble Peroxyoamid Reagent: Evalulation for Fluorescent Silica Nano-Particles Chemilumineacence

Rastogi S.K., Fianaloski B., Mishra N.N., Cameron E., Bitterwolf T.E., Branen A.L., Maki W.C., University of Idaho, US

Chemiluminescence methods, both enzymatic and non-enzymatic, are widely used as an analytical tool in various bio-molecular detection applications. Advantages of using chemiluminscence detection are its practical simplicity, relatively low back ground interference, high sensitivity compared [...]
