Formation of quantum structures on a single nanotube by modulating hydrogen adsorption
(American Physical Society, 2003)Using first-principles density functional calculations we showed that quantum structures can be generated on a single carbon nanotube by modulating the adsorption of hydrogen atoms. The band gap of the hydrogen-free zone ... -
Influence of channel layer thickness on the electrical performances of inkjet-printed In-Ga-Zn oxide thin-film transistors
(IEEE, 2010-12-10)Inkjet-printed In-Ga-Zn oxide (IGZO) thin-film transistors (TFTs) with bottom-gate bottom-contact device architecture are studied in this paper. The impact of the IGZO film thickness on the performance of TFTs is investigated. ... -
Investigation of high frequency performance limit of graphene field effect transistors
(AIP Publishing LLC, 2010)Extremely high field effect mobility together with the high surface coverage makes graphene a promising material for high frequency electronics application. We investigate the intrinsic high frequency performance limit of ... -
Metal nanoring and tube formation on carbon nanotubes
(American Physical Society, 2002)The structural and electronic properties of aluminum-covered single-wall carbon nanotubes (SWNT's) are studied from first principles for a large number of coverages. Aluminum-aluminum interaction, that is stronger than ... -
Oxygenation of carbon nanotubes: Atomic structure, energetics, and electronic structure
(American Physical Society, 2003)This paper presents an extensive and systematic analysis of the oxygenation of semiconducting and metallic single-wall carbon nanotubes by using the first principles pseudopotential plane wave method. Our study involves ... -
Parametric nonlinear lumped element model for circular CMUTs in collapsed mode
(2014)We present a parametric equivalent circuit model for a circular CMUT in collapsed mode. First, we calculate the collapsed membrane deflection, utilizing the exact electrical force distribution in the analytical formulation ... -
Plasmonically enhanced hot electron based photovoltaic device
(Optical Society of American (OSA), 2013)Hot electron photovoltaics is emerging as a candidate for low cost and ultra thin solar cells. Plasmonic means can be utilized to significantly boost device efficiency. We separately form the tunneling metal-insulator-metal ... -
Plasmonics: merging photonics and electronics at nanoscale dimensions
((AAAS) American Association for the Advancement of Science, 2006)Electronic circuits provide us with the ability to control the transport and storage of electrons. However, the performance of electronic circuits is now becoming rather limited when digital information needs to be sent ... -
Systematic study of adsorption of single atoms on a carbon nanotube
(American Physical Society, 2003)We studied the adsorption of single atoms on a semiconducting and metallic single-wall carbon nanotube from first principles for a large number of foreign atoms. The stable adsorption sites, binding energy, and the resulting ... -
Theoretical study of Ga-based nanowires and the interaction of Ga with single-wall carbon nanotubes
(American Physical Society, 2004)Gallium displays physical properties which can make it a potential element to produce metallic nanowires and high-conducting interconnects in nanoelectronics. Using first-principles pseudopotential plane method we showed ... -
Use of side-chain for rational design of n-type diketopyrrolopyrrole-based conjugated polymers: what did we find out?
(The Owner Societies, 2014)The primary role of substituted side chains in organic semiconductors is to increase their solubility in common organic solvents. In the recent past, many literature reports have suggested that the side chains play a ...
