Circuit and system implementations of molecular devices
(IEEE, 2009)We illustrate a couple of circuit implementations of molecular devices, chosen as representative examples in the growing field of molecular electronics. On the one side, we discuss the performance of organic thin film ... -
Multi ion-sensor arrays: Towards an “electronic tongue”
(IEEE, 2016)In this work ion-selective arrays based on spray-coated electrolyte-gated carbon-nanotube field-effect transistors will be used in an example application for water quality assessment. Several cations like Na+, K+, Ca2+ and ... -
Using variable threshold displacement energy for degradation fitting of particle irradiated multi-junction space solar cells
(IEEE, 2016)The degradation of Ga0.5In0.5P/GaAs/Ge triple junction 3G28, 3G30 and isotype 3G28 Ga0.5In0.5P and GaAs cells is analysed and the characteristic degradation curves are determined. The well established displacement damage ... -
Conductive AFM of transfer printed nano devices
(IEEE, 2012)Nano diodes show great potential for applications in detectors, communications and energy harvesting. However, to make them suitable for low-cost mass production, these nano devices have to be fabricated reliably over large ... -
Simulation of carrier relaxation in hot carrier solar cells
(IEEE, 2012)Hot carrier solar cells depend critically on the energy relaxation dynamics of photo-generated carriers in an absorber material, where hot carriers are extracted through energy selective contacts. Here we combine ensemble ... -
Nanopatterning of P3HT:PCBM for organic solar cell realization
(Institute of Electrical and Electronics Engineers Inc., 2016)Organic solar cells (OSC) are becoming an important alternative to standard inorganic ones since they have many intrinsic advantage, such as light weight, flexibility, and low fabrication costs. The use of plasmonic ... -
Modeling and simulation of In1−xGaAsx nanowire solar cells
(IEEE, 2015)In this paper, we investigate the electrical and optical properties of novel InGaAs nanowire solar cells. Key features like high optical absorption and excellent charge carrier mobility make them an attractive candidate ... -
Pattern generation by using high-resolution nanoimprinting and nanotransfer printing techniques
(IEEE, 2009)Nanofabrication is the core task performed and constantly further developed by todays and future semiconductor industry. Optimization of throughput and minimizing process cost and complexity thus increasing fabrication ... -
Modular framework for molecular-FET device-to-circuit modeling
(IEEE, 2015)Recently, several molecular devices have been realized with interesting properties like conductance, switching, gate modulation and negative differential resistance. In this paper we present a new modular framework based ... -
Complex impedance characterization of highly sensitive carbon nanotube gas sensors
(Institute of Electrical and Electronics Engineers Inc., 2014)Complex impedance spectroscopy is used to characterize carbon nanotube (CNT) based gas sensors under the exposure of different concentrations of NH3 (10 ppm, 25 ppm, 50 ppm and 100 ppm). The characterization is performed ...
