Thermodynamics of Extra-Toughness and Hidden-Length in Polymeric Materials with Sacrificial Bonds

Romain Jorge Do Marco, Stefano Giordano

Sacrificial bonds have been observed in several biological materials and structures and can increase their toughness, i.e., their resistance to fracture. They provide a reversible mechanism for dissipating mechanical energy before the possible system rupture. From a structural point of view,...

Coupling Capacitively Distinct Mechanical Resonators for Room-Temperature Phonon-Cavity Electromechanics

Alok Pokharel, Hao Xu, Srisaran Venkatachalam, Eddy Collin, Xin Zhou

Coupled electromechanical resonators that can be independently driven/detected and easily integrated with external circuits are essential for exploring mechanical modes based signal processing and multifunctional integration. One of the main challenges lies in controlling energy transfers between...

In-plane InGaAs/Ga(As)Sb nanowire based tunnel junctions grown by selective area molecular beam epitaxy

Alexandre Bucamp, Christophe Coinon, Sylvie Lepilliet, David Troadec, Gilles Patriarche, M Diallo, Vanessa Avramovic, Kamel Haddadi, X. Wallart, L. Desplanque

In-plane InGaAs/Ga(As)Sb heterojunction tunnel diodes are fabricated by selective area molecular beam epitaxy with two different architectures: either radial InGaAs core/Ga(As)Sb shell nanowires or axial InGaAs/GaSb heterojunctions. In the former case, we unveil the impact of strain relaxation and...

Chapter 3. Surface modification of silicon nanowires for biosensing

Yannick Coffinier, Rabah Boukherroub

Silicon nanowires (Si NWs) are one of the most important one-dimensional semiconductors, partly due to their ready implementation in modern technology. As sensing applications using Si NWs increase, it is necessary to have well-defined chemical attachment schemes that will provide the desired...
