We give a brief overview of the electric-field induced optical second-harmonic generation
(EFISHG) technique that has been used to study the complex behaviors of organic-based …

The turn of this century has undoubtedly brought in tremendous interest in the development
of organic electronic and photonic devices. As an aid of understanding the physics behind …

It is demonstrated that dipolar doping of hole transport layers (HTLs) controls the density and
polarity of the accumulated charge at the critical interface between the HTL and the emission …

Spontaneous orientation polarization (SOP) is inherent in the evaporated films of many
organic semiconducting molecules with a permanent dipole moment. A significant electric …

A tris (7-propyl-8-hydroxyquinolinato) aluminum [Al (7-Prq) 3] film shows negative giant
surface potential (GSP) because of spontaneous orientation polarization. The polarity of this …

Polyelectrolyte gel diodes that are double layers of two oppositely charged polyelectrolyte
gels, sandwiched by two symmetric electrodes, are emergent ionic devices. These diodes …

We report the observation of a magnetocapacitance effect at the interface between Ni and
epitaxial nonpolar BiInO3 thin films at room temperature. A detailed surface study using X …

Sum-frequency generation (SFG) is a wave mixing process in which two input waves at
angular frequencies ω 1 and ω 2 interact in a medium and generate an output at ω 3= ω 1+ …

By using time-resolved electric-field-induced optical second-harmonic generation (EFISHG)
measurements, we directly probed carrier transients in double layer (α-NPD/Alq3) organic …

Electric-field-induced doubly resonant sum-frequency generation (EFI-DR-SFG)
spectroscopy was used to study the electric field distribution in multilayer organic light …
