Successive spray deposition of P3HT/PCBM organic photoactive layers: Material composition and device characteristics
Controlling the active layer composition in organic electronic devices represents one of the major challenges in their fabrication. In particular, the composition of mixed donor/acceptor active layers for photosensitive ...
Conductive AFM of transfer printed nano devices
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 ...
2-D finite-element modeling of ZnO schottky diodes with large ideality factors
In this paper, we complement our previous work on the study of low-temperature rectifying junctions based on Ag/ZnO Schottky barriers. Diodes characterized by very high I /I ratio and ideality factors considerably higher ...
Stochastic wave sensing with logarithmic periodic circular antenna arrays
Time-domain electromagnetic interference (EMI) measurement systems sample the broadband EMI signal with GHz sampling rates. Direction of incidence resolved EMI measurements are of great interest in open area test sites. ...
Quantum dynamics of circuits with memory capacitors and inductors
The quantum mechanical rate equations for a general class of circuits consisting of lossless memory elements embedded in a general lossless linear reciprocal circuit have been derived. The embedding circuit is described ...
Nano-transfer printing of functioning MIM tunnel diodes
Nano diodes show great potential for applications in detectors, communications and energy harvesting. In this work, we focus on nano transfer printing (nTP) to fabricate nm-scale diodes over extensive areas. Using a ...
Sensing of stochastic waves with logarithmic periodic linear antenna arrays
Time-domain electromagnetic interference (EMI) measurement systems sample the broad-band EMI signal with GHz sampling rates and compute the EMI spectrum by digital signal processing. This yields not only a reduction of the ...
Sensing of stochastic waves with circular antenna arrays
In this work we present the wideband time-domain analysis of the direction characteristics of circular antenna arrays used for electromagnetic interference sensing. We compute the directivity of circular sensor arrays for ...
Nanomorphology tuning of the thermal response of TiO2/SiO2 Bragg stacks
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2012)
Herein, we present a comparative study of thermo- and environmentally responsive TiO2/SiO2 one-dimensional photonic crystals (Bragg stacks) fabricated by different deposition methods and fabrication schemes, featuring ...
