Open AccessLinear optical response from the odd-parity Bardasis-Schrieffer mode in locally non-centrosymmetric superconductors
On the recent report of a field-induced first order transition in the superconducting state of CeRh2As2, which is a possible indication of a parity-switching transition of the superconductor, the microscopic phys...

Ternary bulk heterojunction for wide spectral range organic photodetectors
Ternary bulk heterojunction (BHJ) system, dual electron donors and an acceptor, was studied for develo** wide spectral range organic photodetectors (OPDs). With two electron donor polymers with different ban...

Vapor-phase-processed fluorinated self-assembled monolayer for organic thin-film transistors
A vapor-phase-processed fluorinated silazane self-assembled monolayer (SAM), 1,3-bis(trifluoropropyl)-1,1,3,3-tetramethyldisilazane (FPDS), was introduced as a surface modifier for pentacene-based organic thin...

Direct top–down fabrication of nanoscale electrodes for organic semiconductors using fluoropolymer resists
We report the use of a fluoropolymer resist for the damage-free e-beam lithographic patterning of organic semiconductors. The same material is also shown to be suitable as an orthogonal electron beam resist fo...

Neutron detectors for scattering experiments at HANARO
Position sensitive detectors (PSD) measure the distribution of scattered neutrons and are essential tools for neutron scattering experiments. Various types of neutron detectors used at neutron diffractometers ...
