Ferroelectric translational antiphase boundaries in nonpolar materials

Nava Setter, Alexander Tagantsev, Alexander Kvasov

Ferroelectric materials are heavily used in electro-mechanics and electronics. Inside the ferroelectric, domain walls separate regions in which the spontaneous polarization is differently oriented. Properties of ferroelectric domain walls can differ from t ...

System-Level Design Considerations for Carbon Nanotube Electromechanical Resonators

Maher Kayal, Jean-Michel Sallese, Marc Pastre, Christian Kauth

Despite an evermore complete plethora of complex domain-specific semiempirical models, no succinct recipe for large-scale carbon nanotube electromechanical systems design has been formulated. To combine the benefits of these highly sensitive miniaturized m ...

High Throughput-Per-Footprint Inertial Focusing

Martinus Adela Maria Gijs, Ata Tuna Ciftlik

Matching the scale of microfluidic flow systems with that of microelectronic chips for realizing monolithically integrated systems still needs to be accomplished. However, this is appealing only if such re-scaling does not compromise the fluidic throughput ...
