In order to enhance the detection capabilities of large-area detectors operating at room temperature, particularly in terms of response time and sensitivity parameters, we have developed an innovative terahertz detector featuring bowtie arrays based on projection micro stereolithography (PμSL). This device integrates the localized surface plasma effect of non-microcavities with the exceptional properties of Weyl semimetal materials within its sub-wavelength structure. To further investigate the detection performance and improve the response time, we have employed a laser field to enhance the surface carrier mobility of the device, thereby enhancing its detection capabilities. At room temperature, the terahertz sensitivity for 0.1 THz has been enhanced from 0.30 MV/W to 0.54 MV/W, representing an 80 % improvement, while the noise equivalent power (NEP) has been reduced from 92 pW/Hz ^1/2 to 50 pW/Hz ^1/2 , marking 45.6% improvement. The response time of the device under external field stimulation is 50 ms. Given the ease and high reproducibility of the ultra-high resolution 3D printing for fabricating microstructures and the straightforward crystallization of WTe ₂ magnetron sputtered thin films, our proposed high-performance terahertz wave photodetector scheme holds promise for effective terahertz wave detection, with potential applications in the realms of 6G communication and terahertz radar.

Information and Communication Technologies (ICTs) applications have become a vital part for MICE industry. MICE higher education is expected to provide their graduates with essential management knowledge and ICTs operational skills to meet the industry demands on the rise. This empirical study investigates the perceptions of employability skills for MICE management in the context of ICTs. Based on the questionnaire (n = 95), an initial 16 employability skills are proposed and the underlying dimensions are explored. The skills of communication, innovation, organizing and coordinating, market promotion, planning, project implementing, crisis management, proficiency in English and operation management are perceived as of great importance. Four categories of employability skills are analysed: Core Generic skills (CGS), Communicative Expression Skills (CES), Practical Hands-on Skills (PHS) and MICE Professional Skills (MPS). This study is crucial as it helps to identify the level of importance and dimension of employability skills for MICE management. For both academia and industry, the results of this study are useful to provide critical skills for multi-skilled and competitive employees for their future success.
