Drawing on the conservation of resource theory, we examined the effect of perceived overqualification on the creative performance via voice toward peers, and how the peer group perceived overqualification moderates the relationship between perceived overqualification and creative performance. We tested this proposal using three waves of lagged data collected from 206 company employees in Shandong Province, China. The results revealed that peer group perceived overqualification moderated the indirect effects of perceived overqualification on creative performance such that there was positive indirect effect via voice toward peers when peer group perceived overqualification is high and negative indirect effect via voice toward peers when peer group perceived overqualification is low. The implications, limitations, and future directions of these findings were discussed.

It is generally believed that having high performance expectations is an effective means of motivating employees to pursue excellence and sustain the motivation driven by it, while ignoring the negative impact that hinders the incentive to sustain such expectations. Drawing on the conservation of resources theory, we constructed a moderated mediation model to examine the relationship between supervisor's high performance expectations and the employee's territoriality utilizing data from 291 supervisor-subordinate dyads from two companies in China. The results revealed that task autonomy moderated the indirect and positive effect of high performance expectations on employees' territoriality through stress, such that this indirect effect was stronger when employees were assigned to higher levels of task autonomy. The theoretical of these findings, as well as future research directions, are discussed.

A room-temperature p-type NiOx film synthesized from a NiC2O4 precursor via hydrothermal treatment is employed as an electron blocking layer (EBL) to fabricate organic photodetectors (OPDs). A simple and efficient calcine process at 375 °C in air decomposes the NiC2O4 particles into NiOx, removes organic components and crystal water, and releases CO2 gas. Our experimental results indicate that this gaseous by-product prevents the agglomeration of NiOx, which yields smaller nanoparticles (5–10 nm). The formation of an EBL at room temperature improves device performance. After optimization, the performance parameters obtained, including dark current density, responsivity, specific detectivity and response, are 1.13 × 10−7 A cm−2, 0.74 A W−1, 3.86 × 1012 Jones, and 0.5/8 ms, respectively. Additionally, the dark current is reduced by more than an order of magnitude after the insertion of the NiOx layer. The proposed simple and easy method for producing an EBL could be beneficial for the commercial low-temperature and large-area preparation of OPDs.
