Abstract
Purpose
The purpose of this paper is to examine the growth and characterization of the two different compound semiconductors, namely, n-zinc oxide (ZnO) and p-gallium antimonide (GaSb). In this paper, fabrication and characterization of n-ZnO/p-GaSb heterojunction diode is analyzed.
Design/methodology/approach
Thermo vertical direction solidification (TVDS) method was used to synthesize undoped GaSb ingot from high purity Ga (5N) and Sb (4N) host materials. Thermal evaporation technique is used to prepare a film of GaSb on glass substrate from the pre-synthesized bulk material by TVDS method. Undoped ZnO film was grown on GaSb film by sol–gel method by using chemical wet and dry (CWD) technique to fabricate n-ZnO/p-GaSb heterojunction diode.
Findings
The formation of crystalline structure and surface morphological analysis of both the GaSb bulk and film have been carried out by x-ray diffraction (XRD) analysis and scanning electron microscopy analysis. From the XRD studies, the structural characterization and phase identification of ZnO/GaSb interface. The current–voltage characteristic of the n-ZnO/p-GaSb heterostructure is found to be rectifying in nature.
Originality/value
GaSb film growth on any substrate by thermal evaporation method taking a small piece of the sample from the pre-synthesized GaSb bulk ingot has not been reported yet. Semiconductor device with heterojunction diode by using two different semiconductors such as ZnO/GaSb was used by this group for the first time.

Abstract
Purpose
The paper aims to explore how market pressures, upper echelons theory and slack resources interact to affect pro-environmental strategies in an emerging market. Specifically, the authors assess external market factors (consumer concerns, regulatory forces and competitors' concerns) in terms of how they are negotiated through internal resources and company capabilities (top management commitment and discretionary slack) to produce or not produce pro-environmental strategies (environmental corporate strategy and environmental marketing strategy).
Design/methodology/approach
A total of 1,000 questionnaires were distributed in the Pakistani manufacturing sector – where energy use and natural resources consumption is intensive. The final 181 useable responses were analyzed using covariance-based structural equation modeling and the PROCESS macro.
Findings
The results reveal that regulatory forces and competitors' concerns have both direct and conditional indirect effects on environmental corporate strategy but only conditional indirect effects on environmental marketing strategies through the mediation of top management commitment and at different levels of discretionary slack. However, consumer concerns remain inconsequential antecedents with insignificant direct effects and conditional indirect effects on environmental corporate and marketing strategies through the mediation of top management commitment at different levels of discretionary slack.
Originality/value
The authors propose an integrative model as a functioning mechanism for the environmental strategic decisions of companies in emerging markets. This model relies on both slack resource and upper echelons theories. These findings contribute to a better understanding of the impacts of internal and external determinants and functions on environmental strategies at corporate and functional levels in emerging markets. The various paths to diverse levels of environmental strategy and the insignificant role of consumer concerns suggest a need for further investigation of corporate environmentalism in emerging markets that consider their distinctive legal, societal, market and institutional contexts.

Abstract
Purpose
Achieving project success is the goal of every project. Due to various project requirements, some of the key determinants of project success cannot be met. The purpose of this paper is to understand relying factors that can lead to a successful project that includes project management maturity, decision-making, coordination and knowledge management.
Design/methodology/approach
A self-administered survey was distributed to 231 project managers in the Malaysian project management community. Analysis using partial least square structural equation modelling was applied in testing the proposed relationship between these latent variables.
Findings
Finding shows that all the hypotheses were supported and significant. The most impactful factor is project management maturity, followed by knowledge management.
Practical implications
Implication to the project management industry includes providing autonomy to individuals involved in their expertise and management of efficient cross-functional teams between teams in the project. A systematic knowledge management system through a central repository would contribute to the efficient and flexible distribution of knowledge throughout the project process.
Originality/value
This study is one of the few studies focussing on determinants of project success in Malaysia.

Abstract
Purpose
The research analyzes the influence of three environmental triggers, i.e. awareness, concern and knowledge on environmental attachment and green motivation that affect tourists' pro-environmental behavior in the Pakistan’s tourism industry. Furthermore, this study has analyzed the moderating role of moral obligation concerning environmental attachment and green motivation on tourists' pro-environmental behavior.
Design/methodology/approach
Data were gathered via a structured questionnaire by 237 local (domestic) tourists of Pakistan. Furthermore, the data were examined by employing SmartPLS.
Findings
Findings demonstrate that all three environmental triggers have a positive and significant relationship with environmental attachment and green motivation. Accordingly, environmental attachment and green motivation promote tourists' pro-environmental behavior. Furthermore, the moderating role of moral obligations has also been incorporated in the study. The finding reveals a strong and positive relationship among environmental attachment and tourists' pro-environmental behaviors during high moral obligations. In contrast, moral obligations do not moderate association between green motivation and tourists' pro-environmental behavior. Therefore, competent authorities should facilitate tourists to adopt environmentally friendly practices; which will ultimately promote pro-environmental behavior.
Originality/value
This study provides useful insights regarding the role of tourism in fostering environmental attachment and green motivation that sequentially influence tourist pro-environmental behavior. Secondly, this research has employed moral obligations as a moderator to identify the changes in tourists’ pro-environmental behavior based on individuals' ethical considerations. Hence, the study provides an in-depth insight into tourists' behavior. Lastly, the present research offers effective strategies for the tourism sector and other competent authorities to increase green activities that can embed the importance of the environment among individuals.
