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.

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.

Using an Atomically Thin Layer of Hexagonal Boron Nitride to Separate Bound Charge-Transfer Excitons at Organic Interfaces

Shanika Wanigasekara et al.

Summary: We successfully used two-dimensional hexagonal boron nitride as an insulator to facilitate the conversion of photons to free carriers at organic donor-acceptor interfaces. Despite lowering the initial electron-transfer rate, the photon-to-free-carrier conversion yield was increased due to a larger charge-separation yield.

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.

Strongly correlated excitonic insulator in atomic double layers

Liguo Ma et al.

Summary: This study demonstrates a strongly correlated two-dimensional excitonic insulator ground state in transition metal dichalcogenide semiconductor double layers, providing direct thermodynamic evidence for the state. Capacitance measurements show that the exciton fluid is compressible but charge-incompressible. An exciton phase diagram reveals both the Mott transition and interaction-stabilized quasi-condensation.

Ultrafast hole transfer from monolayer ReS2 to thin-film F8ZnPc

Pavel Valencia-Acuna et al.

Summary: In the heterostructure of 1T'-ReS2 and F8ZnPc, holes in ReS2 can efficiently transfer to F8ZnPc on a timescale shorter than 0.35 ps with a long lifetime in F8ZnPc. The lack of electron transfer confirms the feasibility of developing 2D/organic heterostructures with anisotropic electronic and optoelectronic properties.

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.
