Incoherent hopping

WebApr 17, 2009 · We present a theory for spin diffusion in disordered organic semiconductors, based on incoherent hopping of a charge carrier and coherent precession of its spin in an effective magnetic field, composed of the random hyperfine field of hydrogen nuclei and an applied magnetic field. From Monte Carlo s … WebThe concept of hopping transport has been familiar for a long time in connection with ionic conduction, since ions move essentially by hopping, whether through interstices or vacancies. This concept has been extended to electrons, particularly for electronic conduction in amorphous and disordered nonmetallic solids. 4, 34

WebFeb 28, 2005 · Conclusions. The electronic structure of FL oligomers provides a means to access the wire-like incoherent hopping regime for hole transport over long distances at nearly constant bridge energy. This property is a consequence of the localization of charge at the two terminal monomers within the F L n + ∙ bridge.

Crystalline solids and molecular solids are two opposite extreme cases of materials that exhibit substantially different transport mechanisms. While in atomic solids transport is intra-molecular, also known as band transport, in molecular solids the transport is inter-molecular, also known as hopping transport. The two different mechanisms result in different charge mobilities. In disordered solids, disordered potentials result in weak localization effects (traps), which reduc… Webin· co· her· ent ˌin-kō-ˈhir-ənt. -ˈher-.
