Herein, to reveal the underlying charge generation mechanisms, we have investigated the exciton binding energy ( E b ) in Y6 by a joint theoretical and experimental study. The results show that owing to strong charge polarization effects, Y6 has remarkable small E b of 11~0.15 eV, which ...
A computation is sketched to determine the relation between binding energy and nonlinearity of a stationary soliton solution for a difference-differential equation of the nonlinear Schrdinger type. AC Scott,L Macneil - 《Physics Letters A》 被引量: 154发表: 1983年 Theory of exciton pair states an...
Photoreflectance evidence of the N-induced increase of the exciton binding energy in an InxGa1−xAs1−yNy alloy The binding energy of the heavy-hole ground-state exciton in In0.25Ga0.75As1−yNy/GaAs single quantum wells (y = 0, 0.011) was experimentally derived ... M Geddo,G ...
Exciton binding energy [58,59] is the hole–electron Coulomb attractive energy, which is closely related to the electron excitation characteristics. Among all, the most influential factor should be the D index. It is easy to understand that the larger the D index is, the greater the distance...
The energy level offset between the molecular orbitals of the donor and acceptor layers provides the driving force for elementary charge transfer (Fig. 1a, process 1). For example, when the lowest unoccupied molecular orbital (LUMO) energy difference is greater than the exciton binding energy, ...
The tight-binding approximation and the recursion method are used to study the size dependence of the band gap for small CdS and ZnS crystallites (20-2500 ... P Lippens,M Lannoo - 《Physical Review B Condensed Matter》 被引量: 1394发表: 1989年 Quantum Size Effects on the Exciton Energy...

The present study of AlnSenclusters (n = 1–5) has been performed using density functional theory. The ground-state structures of these clusters along with low-lying isomers are explored. The stabilities of clusters are analysed by calculating their binding energy per atom and dissociation en...
Z3 also exhibits low exciton binding energy (Eb = 0.32 eV). Moreover, Z1 has excellent charge mobilities owing to the lowest hole mobility (λh = 0.0078) and electron mobility (λe = 0.0088). Among all Z1 has an elevated value of VOC and PCE accountable for more ...
efficiency of exciton Under short-circuit condition, the ratios were 0.93, 0.95 and 0.96 for BTID-0F, BTID-1F and BTID-2F, suggesting the effective exciton dissociation of the three molecules, especially for BTID-1F and BTID-2F. Under maximal power output circumstances (Veff ¼ 0.2 V)...
