Unipolar barriers in near-broken-gap heterostructures for high-performance self-powered photodetectors

Yong Yan, Jie Li, Hengyi Li, Shasha Li, Zhongwei Li, Wei Gao, Yurong Jiang, Xiaohui Song, Congxin Xia, Jingbo Li

Summary: In this study, a high-performance self-powered broadband photodetector was fabricated based on a near-broken-gap GeSe/SnS2/InSe heterostructure. The device exhibited ultrahigh open-circuit voltage, high power-dependent responsivity, and fast response time in the self-powered mode. By utilizing the near-broken band alignment and the high electron mobility of InSe layer, the conversion efficiency of the device was improved. The unipolar hole barrier at the interface also inhibited the Langevin recombination, leading to the enhancement of open-circuit voltage. This work provides an opportunity for the realization of high-sensitivity polarization-sensitive broadband photodetectors.

Revealing Atomic-Level Surface Passivation of PbI2-Reconditioned Red Perovskite Quantum Dots

Liuli Yang, Jianhua Huang, Zheyuan Xu, Yang Li, Shijin Hou, Yike Tan, Juan Du, Xiao Wang, Ziwei Li, Anlian Pan

Summary: CsPbI3 perovskite quantum dots (QDs) have great potential as high-efficiency and low-cost red fluorophores in advanced display and light-sensing applications. However, their structural and spectral stabilities are seriously compromised in water or light environments. This study demonstrates a compositional engineering strategy with an additional PbI2-recondition process to synthesize highly-stable CsPbBr1.2I1.8 @ SiO2 QDs, improving the spectral stability and exciton binding energy. High-resolution structure characterizations and element distribution analysis provide strong evidence that PbI2-recondition can repair defects, leading to perfect lattices and homogeneous SiO2 passivation layers. The proposed recondition strategy opens up a new avenue for stable and high-quality red perovskite QDs for new-generation lighting and light-sensing devices.

Directional Charge Transfer Channels in a Monolithically Integrated Electrode for Photoassisted Overall Water Splitting

Bo Li, Zhi Tian, Lei Li, Yu-Han Wang, Yuan Si, Hui Wan, Jinghui Shi, Gui-Fang Huang, Wangyu Hu, Anlian Pan, Wei-Qing Huang

Summary: In this study, directional charge transfer channels were constructed using carbon dots/carbon nitride (CCN) nanotubes and FeOOH/FeCo layered double hydroxide (FFC) nanosheets, which significantly improved the photo-assisted overall water splitting performance. Experimental investigations and DFT calculations demonstrated that the interfacial C-O-Fe bonds between CCN and FFC served as charge transfer channels, facilitating the migration of photoexcited carriers between their surfaces. The in situ oxidized Fe/Co species triggered lattice oxygen activation, leading to the construction of the Fe-Co dual-site as the catalytic center and effectively lowering the energy barrier for water oxidation. As a result, the CCN@FFC electrode exhibited multiple functionalities in photoelectrocatalysis, achieving low overpotentials for photo-assisted hydrogen evolution, oxygen evolution, and overall water splitting.

Observation and Modulation of High-Temperature Moire-Locale Excitons in van der Waals Heterobilayers

Cuihuan Ge, Danliang Zhang, Feiping Xiao, Haipeng Zhao, Mai He, Lanyu Huang, Shijin Hou, Qingjun Tong, Anlian Pan, Xiao Wang

Summary: Transition metal dichalcogenide heterobilayers exhibit strong moire potentials that can trap interlayer excitons at different locations within one moire unit cell. In this study, high-temperature interlayer excitons trapped at separate moire locales in WS2/WSe2 heterobilayers are observed and modulated. The emission of these excitons can be controlled through engineering the heterointerface with different phonon scattering and the emission energy can be further modulated via strain engineering. These highly tunable interlayer excitons provide valuable insights into moire-exciton physics and have potential applications in high-temperature excitonic devices.

Summary: In this study, we modulate the photoluminescence emissions of interlayer and intralayer excitons in WSe2/WS2 heterostructures using different stacking configurations. Temperature and power dependent spectroscopy reveal the suppression of interlayer exciton formation at high temperatures and the dominance of intralayer excitons under certain doping conditions. Our results contribute to the understanding of the interaction between interlayer and intralayer excitons in WSe2/WS2 heterostructures and have potential applications in excitonic devices.

Continuous-Wave Multiphoton-Induced Electron Transfer in Tunnel Junctions Driven by Intense Plasmonic Fields

Chenfang Lin, Faruk Krecinic, Hiroko Yoshino, Adnan Hammud, Anlian Pan, Martin Wolf, Melanie Mueller, Takashi Kumagai

Summary: In this study, we demonstrate the generation of multiphoton photocurrents in a plasmonic scanning tunneling microscope (STM) junction using continuous-wave excitation. The photocurrent shows a power-law dependence on the incident intensity, with the exponent varying between 3 and 1 depending on the photon energy and bias voltage. The bias-voltage dependence of the photocurrent exhibits characteristic steps that can be explained by the transmission of nonthermal carriers through the potential barrier of the tunnel junction.
