Observation of Induced Modulation Instability of an Incoherent Optical Beam
We observe induced modulation instability (MI) of a partially spatially incoherent beam by seeding noise through cross-phase-modulation. Experiments revealed the existence of a threshold for such induced incoh...

Chapter
Outlook
Modeling the charge transport in organic materials is a formidable task due to the complexity in dealing with various scattering mechanisms, which is intrinsically a many-body problem [1]. In this book, we pre...

Deformation Potential Theory
When the electron–phonon coupling is weak compared with the intermolecular electronic couplings, charge transport can be described by the band mechanism. Namely, the charge moves coherently in a wavelike manne...

Chapter
Polaron Mechanism
The intrinsic charge transport in organic semiconductors is an electron–phonon interacting process. Due to the “soft” nature of organic materials, the existence of an electron can cause significant deformation...

Chapter
Hop** Mechanism
In the limit of strong electron–phonon coupling and weak intermolecular electronic coupling, a charged molecule undergoes a large geometry relaxation, which eventually traps the charge. In this case, the charg...
