The performance of bulk heterojunction organic solar cells made of conjugated polymers/oligomers and fullerenes has significantly improved in the last few years (with PCE exceeding 10%).1 Experiments suggest that the intermolecular interactions between polymers and fullerenes are critical to the design of (even) more efficient organic photovoltaic cells.2 However, a detailed understanding of...

Light-emitting conjugated polymers can be electrochemically p- and n-doped in situ in a device called the polymer light-emitting electrochemical cell (PLEC). [1] Electroluminescence occurs through the injection of minority charge carriers when the doped polymers make contact and...

Two-dimensional void inclusion phononic crystal waveguide structures on gallium arsenide (GaAs) can be used to control surface acoustic waves (SAWs). In GaAs, SAWs create a piezoelectric field, providing a dynamic spatial confinement potential of electron/holes, which can then be implemented to transport charge and potentially spin. This work develops the first phononic crystal technology in...

Spin current transport generated by spin pumping was investigated in magnetic single py (Ni80Fe20)/Ta and double py/Ta/py/Fe layer structures prepared by magnetron sputtering. Ferromagnetic Resonance (FMR) generates rf pure spin current at the py/Ta interface. This leads to an interface Gilbert damping $\alpha_{sp}$ characterized by the spin mixing conductance parameter $g_{\uparrow...

Microcavity polaritons are a hybrid photonic system arising from the strong coupling of cavity photons to quantum-well excitons. The light-matter nature of polaritons introduces a Kerr-like nonlinearity while still being easily accessible by standard optical means. The ability to engineer confinement potentials in microcavities makes polaritons a convenient system to study spatially localized...

When electronic channels compete to screen a single impurity spin, as in the one- and two-channel Kondo model, a ground state with nontrivial entanglement structure is expected to arise. We exploit a spin-chain representation of both the one- and two-channel Kondo model to probe the ground-state block entropy, negativity, tangle, and Schmidt gap, using a density matrix renormalization group...

We propose a dynamic nuclear polarization technique at high field and at cryogenic condition in order to highly polarize a nano-meter ensemble of protons with high efficiency. The proposed experiment is particularly designed as an initialization step for ultra-sensitive magnetic resonance imaging (MRI) and spectroscopy using silicon nanowire mechanical oscillator in order to enhance the image...

Organic semiconductors are quite promising for the field of photovoltaics, light-emitting diodes, flexible electronics and biosensors/electronics. However, poor charge mobility that comes along with their amorphous nature, and/or their susceptibility to photodegradation especially in the presence of oxygen and moisture, and poor repeatability of characteristics have been some of the common...
