Thermal treatment and encapsulation of carbon nanotube based temperature sensors
(IEEE, 2015)We present high-performance temperature sensors which utilize spray deposited carbon nanotube (CNT) films as the active sensing material. In order to evaluate the device performance, the change in device resistance with ... -
Kinetic Monte Carlo modeling of low-bandgap polymer solar cells
(Institute of Electrical and Electronics Engineers Inc., 2014)Numerical simulations based on kinetic Monte Carlo (kMC) techniques provide a powerful and versatile tool to gain a deep understanding of nanoscale processes in bulk organic heterojunction (BHJ) solar cells and to guide ... -
Modeling and parametric simulation of triple junction solar cell for space applications
(Institute of Electrical and Electronics Engineers Inc., 2014)In this paper a calibrated model of a III-V triple junction solar cell is presented. The simulations are carried out with a commercial TCAD software, and the model is validated by a comparison of the EQE and IV curve with ... -
Application of mismatched cellular nonlinear networks for physical cryptography
(IEEE, 2010)This paper proposes the use of Cellular Non-Linear Networks (CNNs) as physical uncloneable functions (PUFs). We argue that analog circuits offer higher security than existing digital PUFs and that the CNN paradigm allows ... -
Si and SiGe based monolithic integrated antennas for electromagnetic sensors and for wireless communications
(IEEE, 2011)Integrated nanoantennas for sensorics and communications on the basis of CMOS circuits, MIM tunnel diodes, and carbon based nanoelectronics as well as methods for modeling of wireless interchip links are discussed. ... -
Boolean and non-Boolean nearest neighbor architectures for out-of-plane nanomagnet logic
(IEEE, 2012)We present the design and simulation of information processing hardware that is comprised of single domain, Co/Pt magnets (i.e., out-of-plane nanomagnet logic - or oNML). We first describe the design and evaluation of oNML ... -
Towards a hybrid CMOS-imager with organic semiconductors as photoactive layer
(IEEE, 2011)Hybrid CMOS-imagers with vertically integrated organic semiconductors are proposed to enhance the currently small fill factor of conventional CMOS-pixels. Organic photodetectors (OPDs) are low-cost and easy processable and ... -
Energy harvesting using nano antenna array
(IEEE, 2011)Nano antenna arrays are excellent devices for infrared detection (terahertz radiation). We present our latest results on the production of nano antennas fabricated in a nano transfer printing process. The molecular beam ... -
Biocompatibility tests on spray coated carbon nanotube and PEDOT:PSS thin films
(IEEE, 2016)Thin films of semiconducting and unsorted carbon nanotubes (CNT) are prepared on a transparent and flexible cyclic olefin polymeric substrate. The CNT biocompatibility is analyzed using L929 mouse fibroblasts and Human ... -
Optimization of organic solar cells by kinetic Monte Carlo simulations
(Institute of Electrical and Electronics Engineers Inc., 2014)Simulations based on kinetic Monte Carlo (kMC) methods provide a powerful and versatile tool to gain a deep understanding of nanoscale processes in organic bulk-heterojunction (BHJ) solar cells and to guide their optimization. ...
