Carbon nanotube based gas sensor arrays on rigid and flexible substrates
(Institute of Electrical and Electronics Engineers Inc., 2015)We report a highly reproducible Carbon nanotube (CNT) based gas sensor arrays, which are able to discriminate between NH3, CO, CO2 and ethanol. Each sensor array is composed of four sensing elements where metallic nanoparticles ... -
On the modeling of radiated EMI on the basis of near-field correlation measurements
(IEEE, 2011)A method for a stochastic treatment of noisy electromagnetic fields is presented. A complete description of stochastic electromagnetic fields is given by the autocorrelation spectrum of the different field variables and ... -
Carbon nanotube based temperature sensors fabricated by large-scale spray deposition
(Institute of Electrical and Electronics Engineers Inc., 2014)We present high-performance temperature sensors which utilize spray deposited carbon nanotube (CNT) films as the active sensing material. In order to evaluate device performance, the change in device resistance with respect ... -
Carbon nanotube based millimeterwave fishnet metamaterials
(IEEE, 2014)Fishnet metamaterials consist of two or more conducting fishnet layers separated by homogeneous dielectric layers. Different from other planar multilayer metamaterial structures fishnet metamaterials do not require vias ... -
Electronic transport modeling with HSPICE in random CNT networks
(IEEE, 2012)A Monte Carlo based computational model was developed to analyze the electrical transport properties in networks of randomly arranged single wall carbon nanotubes. The CNTs are modeled as stiff sticks with a lognormal ... -
Error analysis of Co/Pt multilayer based Nanomagnetic Logic
(IEEE, 2011)Nanomagnetic Logic (NML) is a novel nanoscale computing paradigm based on field-coupled single-domain nanomagnets. Most of the studies so far have been focused on permalloy, where the easy axis of magnetization is in-plane. ... -
Deposition of PdAu thin films sectioned by sub-15-nm gaps on silicon using direct nanotransfer printing
(IEEE, 2008)We have demonstrated direct nanoscale transfer printing of PdAu lines from a hard mold onto a hard substrate at room-temperature without employing any flexible buffer layers or organic adhesion promoters or release agent ... -
Towards the optimization of organic solar cells via controlled morphologies
(IEEE, 2009)We present a combined experimental and theoretical analysis of organic solar cells based on bulk heterojunctions. Our simulation based on a drift-diffusion approach shows that a cell with controlled morphology can lead to ... -
Electroluminescence and photoluminescence characterization of multijunction solar cells
(IEEE, 2012)A combined electroluminescence and photoluminescence setup for a fast, nondestructive, and high-resolution characterization of large-area lattice matched GaInP /Ga(In)As/Ge triple-junction space solar cells was developed. ... -
Comparative analysis of THz quantum cascade lasers
(IEEE, 2007)We present a comparative Monte-Carlo analysis of a set of GaAs-based THz quantum cascade lasers, allowing us to identify the effects limiting the device performance in the threshold region. Reasonable agreement with ...
