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 ... -
Design of a systolic pattern matcher for Nanomagnet Logic
(IEEE, 2012)Nanomagnet Logic (NML) is widely considered to be one of the promising for "beyond-CMOS" nanoscale architectures. So far only relatively simple circuits (nanomagnetic logic gates and adders) have been studied experimentally ... -
Switching behavior of lithographically fabricated nanomagnets for logic applications
(2012)The switching behavior and the magnetization states of non-interacting Supermalloy (Ni Fe Mo ) nanomagnet arrays were studied by magnetic measurements and micromagnetic simulations. The switching-field distribution of the ... -
Sensing of stochastic waves with logarithmic periodic linear antenna arrays
(IEEE, 2012)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
(IEEE, 2012)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 ... -
Role of defect relaxation for trap-assisted tunneling in high-kappa thin films: A first-principles kinetic Monte Carlo study
(AMER PHYSICAL SOC, 2012)We assess the impact of structural relaxation of defects upon charging on trap-assisted tunneling in high-kappa dielectric materials. ZrO(2)/Al(2)O(3)/ZrO(2) thin films are taken as an exemplary system. In our completely ... -
Computational study of domain-wall-induced switching of Co/Pt multilayer
(IEEE, 2012)Nanomagnet logic (NML) emerges as a new field of spintronics. For NML operation, strong external magnetic clocking field pulses are required. The power-efficient generation of such fields is a challenge for magnetic ... -
A hybrid CMOS-imager with a solution-processable polymer as photoactive layer
(2012)The solution-processability of organic photodetectors allows a straightforward combination with other materials, including inorganic ones, without increasing cost and process complexity significantly compared with conventional ...
