Improved terahertz quantum cascade laser with variable height barriers
(2012)Using an ensemble Monte-Carlo analysis, it is found that relaxing the constraint of identical barrier heights can result in an improved temperature performance. Exploiting this additional design degree of freedom, modified ... -
The influence of electrical effects on device performance of organic solar cells with nano-structured electrodes
(NATURE PUBLISHING GROUP, 2017)Integration of light-trapping features and exploitation of metal nanostructure plasmonic effects are promising approaches for enhancing the power conversion efficiency of organic solar cells. These approaches' effects on ... -
Applications of high-capacity crossbar memories in cryptography
(2011)This paper proposes a new approach for the construction of highly secure physical unclonable functions (PUFs). Instead of using systems with medium information content and high readout rates, we suggest to maximize the ... -
Modeling of leakage currents in high-k dielectrics: Three-dimensional approach via kinetic Monte Carlo
(2010)We report on a simulation algorithm, based on kinetic Monte Carlo techniques, that allows us to investigate transport through high-permittivity dielectrics. In the example of TiN/ ZrO /TiN capacitor structures, using ... -
Modeling bound-to-continuum terahertz quantum cascade lasers: The role of Coulomb interactions
(2010)Based on an ensemble Monte Carlo analysis, we show that Coulomb interactions play a dominant role in bound-to-continuum terahertz quantum cascade lasers and thus require careful modeling. Coulomb interactions enter our ... -
Nano antenna array for terahertz detection
(2011)Infrared (IR) detectors have been fabricated consisting of antenna-coupled metal-oxide-metal diodes (ACMOMDs). These detectors were defined using electron beam lithography with shadow evaporation metal deposition. They are ... -
Nanoelectronics-based integrate antennas
(2010)Nanoelectronics is the gateway to a variety of novel electronic devices and systems with substantially new properties. It enables the development of nanoscale electronic devices, covering radio frequencies in the terahertz ... -
Coupled carrier-field Monte-Carlo analysis of mid-IR quantum cascade lasers
(IEEE, 2010)A short-injector mid-infrared quantum cascade laser based on the In 0.6Ga0.4As/In0.365Al0.635As material system is analyzed by means of a self-consistent ensemble Monte-Carlo method. Scattering mechanisms, namely electron ... -
Monolithic integrated antennas and nanoantennas for wireless sensors and for wireless intrachip and interchip communication
(IEEE, 2010)Monolithic integrated antennas and nanoantennas based on silicon technology, carbon nanotubes, graphene, and nanostructure thin film technology are discussed. Monolithic integration of antennas and novel nanoelectronic ... -
