Interaction. Excitons are the mainmechanism for light emission in semiconductors at low temperature(when the characteristic thermal energy kT is less than the exciton binding energy), replacing the free electron-hole recombination at higher temperatures. What are excitons explain? An exciton isa bound ...
Product Jahn-Teller systems: The {T1H}(g+2h) icosahedral exciton In this paper we examine the structure of the resulting potential energy surface. The treatment first considers the simplified {T1H}(2h) problem. The ... QC Qiu,LF Chibotaru,A Ceulemans - 《Physical Review B》 被引量: 2...
The energy transfer distances provided by these structural considerations provide a blueprint for future theoretical studies aimed at further elucidating relevant pathways culminating in exciton transfer to P840, facilitating the initiation of the RC charge-separated state. Figure 5. Potential pathways of...
In some cases, these two particles exist in a bound state, forming a single quasi-particle known as an exciton. Within an exciton, the electron and hole are bound together by Coulombic interactions, and the strength of this bond is quantified by its exciton binding energy. Formation of ...

Carlos Ghosn is widely viewed as having been the glue that kept the alliance together Can the alliance survive? Ghosn, accused of with breach of trust and under-declaring his income, had been seen as the glue binding together the complex three-way structure that makes up the world's top-se...
