is constructed by utilizing an integrated nanosystem consisting of an energy harvesting or storage unit and a light sensor. The simplified structure and maintenancefree features of the first category endow the low-cost advantage as compared with the second one. Furthermore, the heterojunction-based PDs generally possess superior performance compared with PEC and the integrated nanosystem. [10,11] In addition, the vertical heterojunction configuration is considered as one of the most essential cornerstones of high performance optoelectronic devices, which is attributed to its strong built-in electric field, the short carrier diffusion path, and the large active area. [12] Although considerable efforts have been devoted, [13-18] the reports on selfpowered broadband PDs remain limited and several challenges are to be solved. For instance, various photoactive materials and methods are applied to construct PDs, but it is still challenging to design a high performance self-powered PDs based on earth abundant materials by a facile method. In addition, several conditions need to be met for the photoactive materials: the large absorption coefficient, the superior carrier mobility, the tunable energy-level alignment with electrode for the sake of high-performance PDs. [5] Thus, it is still demanding to find suitable photoactive materials for PDs that can work at room temperature in the range from UV to NIR. Metal chalcogenides semiconductors are promising candidates for photoelectric devices owing to their specific electronic and optoelectronic properties. [19,20] Tin disulfide (SnS 2) is an indirect bandgap (2.2 eV) semiconductor, which has drawn considerable attentions owing to its advantages of low cost, earth abundance, nontoxicity, and environmental friendliness. [21] The absorption coefficient and carrier mobility is up to 10 5-10 6 cm −1 and 230 cm 2 V −1 s −1 , respectively. [5,22] SnS 2based PDs have shown superior performance, such as high on/off ratio, high responsivity, good stability, and fast response speed. [22-25] In addition, it has been proved that SnS 2 can be applied to construct a PD in the range from UV to NIR light, although it need to be powered externally. [26] Zinc oxide (ZnO), a typical n-type wide bandgap semiconductor, has already been widely applied in optoelectronic devices due to its wide bandgap and high exciton biding energy. [27-29] In addition, ZnO-based PDs are endowed the advantages of low applied field, fast response, and no oxygen dependency. [30,31] On the other hand, the doping of S atom can not only improve the optical and electrical properties of ZnO, but also modify the band structure of Self-powered photodetectors that can work without an external power source are expected to play a crucial role in future optoelectronic devices. Herein, SnS 2 /ZnO 1−x S x heterojunctions are fabricated by a facile sputtering method and constructed as self-powered broadband photodetectors covering from UV (365 nm) to NIR (850 nm). The self-powered device shows a superior responsivity of 8.28 mAW...
This is the first electroencephalogram study exploring the personal perspective effect on wise advising. Participants advised hypothetical protagonists in life dilemmas from both the 2nd- and 3rd-person perspective. Their advice for each dilemma was rated by two independent raters on wisdom criteria, i.e., metacognitive humility, metacognitive flexibility, and perspective taking. The results revealed that participants felt a significantly shorter psychological distance from protagonists when advising from the 2nd- (vs. the 3rd-) person perspective, p < 0.001. However, there was no significant effect of perspective condition on the wisdom score. Nevertheless, stronger resting-state absolute EEG powers in the frontal lobe were associated with wiser advising from the 2nd-, but not the 3rd-person perspective. Moreover, Z tests revealed that the correlations between the resting-state absolute EEG powers and wisdom scores were significantly stronger during advising from the 2nd- than the 3rd-person perspective. These results suggest that advising from the 2nd-person perspective was more self-related, and mental activities during rest contributed to advising from the 2nd- but not the 3rd-person perspective.
Scholars within the Berlin paradigm have analysed participants' responses to a hypothetical vignette about a friend's suicide ideation. However, no study has yet focused on participants' emotional reactions to this scenario, an important aspect of wisdom performance. We conducted a Thin‐Slice Wisdom study where participants were asked to give advice to a hypothetical friend contemplating suicide. We analysed their emotional profiles using facial expression analysis software (FACET2.1 and FACEREADER7.1). Participants' verbal responses were also transcribed and then scored by 10 raters using the Berlin criteria. Results revealed that the sadder the participants felt, the wiser their performance. Wiser participants may have been better at exploring this sad, but true, existential human dilemma.
The authors develop a plasma-free metalorganic chemical vapour deposition method to grow N-doped p-type ZnO films. The incorporation of the N acceptor and the corresponding change in the Fermi level are well confirmed by x-ray photoelectron spectroscopy. Temperature-dependent photoluminescence reveals the acceptor-related emissions, namely, neutral acceptor-bound exciton and probably donor-acceptor pair transition. In addition, typical rectifying I -V characteristics and room-temperature electroluminescence from ZnO homojunction light-emitting diodes are demonstrated.
Abstract. Background: High school and university teachers need to advise students against attempting suicide, the second leading cause of death among 15–29-year-olds. Aims: To investigate the role of reasoning and emotion in advising against suicide. Method: We conducted a study with 130 students at a university that specializes in teachers' education. Participants sat in front of a camera, videotaping their advising against suicide. Three raters scored their transcribed advice on "wise reasoning" (i.e., expert forms of reasoning: considering a variety of conditions, awareness of the limitation of one's knowledge, taking others' perspectives). Four registered psychologists experienced in suicide prevention techniques rated the transcripts on the potential for suicide prevention. Finally, using the software Facereader 7.1, we analyzed participants' micro-facial expressions during advice-giving. Results: Wiser reasoning and less disgust predicted higher potential for suicide prevention. Moreover, higher potential for suicide prevention was associated with more surprise. Limitations: The actual efficacy of suicide prevention was not assessed. Conclusion: Wise reasoning and counter-stereotypic ideas that trigger surprise probably contribute to the potential for suicide prevention. This advising paradigm may help train teachers in advising students against suicide, measuring wise reasoning, and monitoring a harmful emotional reaction, that is, disgust.
