ABSTRACT
Purpose The study aimed at identifying job insecurity during COVID-19 as a determinant of green entrepreneurial intentions under the mediating role of entrepreneurial passion. Further, moderated mediation model of environmental consciousness and environmental knowledge on the relationship between job insecurity during COVID-19 and green entrepreneurial intentions through entrepreneurial passion as a mediator is also measured. Design/methodology/approach The study employed Statistical Package for the Social Sciences (SPSS) and analysis of a moment structure (AMOS) to calculate the measurement and structure model. Data was collected from the twin cities of Pakistan (Islamabad and Rawalpindi). A total of 389 usable responses were included in the analyses. Findings Considering entrepreneurship as a process, the result shows a significant relationship between the study variables. Also, it is realized that entrepreneurial passion serves as an important mediator between job insecurity during COVID-19 and green entrepreneurial intention. Both entrepreneurial knowledge and environmental consciousness have an indirect conditional effect on the relationship between job insecurity during COVID-19 and green entrepreneurial intention with entrepreneurial passion as a mediator. The study tested a novel relationship between job insecurity during COVID-19 and entrepreneurial passion under the lens of contingency theory and entrepreneurial event theory. Research limitations/implications The extreme necessity to choose an alternative to full-time jobs is entrepreneurial endeavors that can be explored by entrepreneurs. Policymakers can capitalize on this scenario by proposing entrepreneurial opportunities which are green as well. The term Green represents an environmental friendly business, which one can start in the context of COVID-19 when everyone is oriented to cleanliness, personal hygiene and environment friendly. Originality/value The study tested a novel relationship between job insecurity during COVID-19 and entrepreneurial passion under the lens of contingency theory and entrepreneurial event theory. It contributes to the present stock of knowledge and understanding of the subject by contextualizing the concept of green entrepreneurial intention.
ABSTRACT
Bipolar junction transistors (BJTs), the basic building blocks of integrated circuits, are deployed to control switching applications and logic operations. However, as the thickness of a conventional BJT device approaches a few atoms, its performance decreases substantially. The stacking of atomically thin 2D semiconductor materials is advantageous for manufacturing atomically thin BJT devices owing to the high carrier density of electrons and holes. Here, an atomically thin n-p-n BJT device composed of heavily doped molybdenum ditelluride (n-MoTe2) and germanium selenide (p-GeSe) sheets stacked over each other by van der Waals interactions is reported. In a common-emitter configuration, MoTe2/GeSe/MoTe2 BJT devices exhibit a considerably high current gain (beta = I-c /I-b = 29.3) at V-be = 2.5 V. The MoTe2/GeSe/MoTe2 BJT device is employed to detect streptavidin biomolecules as analytes within m. Such vdW BJT devices can trigger the development of state-of-the-art electronic devices that can be used as biosensors to detect the various kinds of target DNA and proteins like spike protein of Covid-19.
