Nanoscale Periodic Trapping Sites for Interlayer Excitons Built by Deformable Molecular Crystal on 2D Crystal

Kushal Rijal et al.

Summary: Periodic nanoscale potentials can trap interlayer excitons by utilizing the structure deformability of a 2D molecular crystal as a degree of freedom. The PTCDI lattice on MoS2 creates a spatial variation of molecular orbital energy, providing effective trapping sites for IXs.

Hybrid Heterostructures to Generate Long- Lived and Mobile Photocarriers in Graphene

Pavel Valencia-Acuna et al.

Summary: We report the generation of long-lived and highly mobile photocarriers in hybrid van der Waals heterostructures that consist of monolayer graphene, few-layer transition metal dichalcogenides, and the organic semiconductor F8ZnPc. Photocarriers in the heterostructures can achieve long recombination lifetimes and high mobility by transferring electrons from F8ZnPc to graphene and separating them from the holes in F8ZnPc. The use of these artificial heterostructures can enhance the performance of graphene-based optoelectronic devices.

Long-Range Hot Charge Transfer Exciton Dissociation in an Organic/2D Semiconductor Hybrid Excitonic Heterostructure

Zukun Wang et al.

Summary: By tracking the characteristic electroabsorption signal from separated charges, this study directly observes the electron-hole pair separation process in an organic/2D semiconductor heterostructure. The study shows that the charge delocalization in organic layers plays a key role in the separation process, while the in-plane delocalization of the 2D semiconductor has negligible contribution. This research is important for the future development of efficient organic/2D semiconductor optoelectronic devices.

Molecular Triplet Sensitization of Monolayer Semiconductors in 2D Organic/Inorganic Hybrid Heterostructures

Lei Ye et al.

Summary: This study investigates the triplet sensitization of monolayer semiconductors and its potential for enhancing optoelectronic applications. The results show that triplet energy or charge can be transferred to the monolayer semiconductors, resulting in photoluminescence enhancement and long-lived charge separation. These findings demonstrate the great promise of molecular triplets in sensitizing 2D monolayer semiconductors and provide guidance for achieving enhanced optoelectronic applications.

Organic-2D Material Heterostructures: A Promising Platform for Exciton Condensation and Multiplication

Kanchan Ulman et al.

Summary: High temperature Bose-Einstein condensation of charge transfer excitons may be achieved in organic-two-dimensional material heterostructures, providing ideal candidates for exciton condensation with long lifetimes and large spatial extents. The emergence of stabilized intermolecular excitons in novel ways suggests design strategies for singlet fission and exciton multiplication, which are important for improving efficiency in solar cells.

Exciton Heating Versus Cooling: Charge Separation Driven by Entropy and Delocalization at Interfaces with Planar Molecules

Tika R. Kafle et al.

Summary: Recent developments in nonfullerene acceptors for organic photovoltaics have led to improved efficiency, with studies showing that charge-transfer excitons undergo a rapid heating process at the donor-acceptor interface, facilitating efficient charge separation. By studying model D-A interfaces, researchers have observed a competition between exciton heating and cooling, with the orientation of D-A molecules playing a key role in determining the direction of this process. Additionally, the presence of bulky side groups and specific molecular orientations are found to be essential in activating exciton heating and promoting charge separation in NFA-based devices.

Type-I Energy Level Alignment at the PTCDA-Monolayer MoS2 Interface Promotes Resonance Energy Transfer and Luminescence Enhancement

Soohyung Park et al.

Summary: The research reveals that PTCDA/ML-MoS2 formed a straddling type-I level alignment supported by insulating sapphire, with PTCDA having the wider energy gap. Resonance energy transfer from PTCDA to ML-MoS2 occurs on a sub-picosecond time scale, enhancing the PL yield from ML-MoS2 and modulating the photoresponse accordingly.
