“…The spectral power density depends on current-fluctuations leading to plasmon creation; small fluctuations in the tunnel current lead to electric field fluctuations, which in turn accelerate and decelerated electrical carriers acting as a plasmon source. As such the spectral dispersion of the internal hybrid plasmon mode is material sensitive [26]. Following this line of thought, our modeling confirms the experimentally observed spectral double peak with exponential decaying emission intensity ( Fig.…”

Electrical-Driven Plasmon Source of Silicon Based on Quantum Tunneling

An efficient silicon-based light source presents an unreached goal in the field of photonics, due to Silicon's indirect electronic band structure preventing direct carrier recombination and subsequent photon emission. Here we utilize inelastically tunneling electrons to demonstrate an electrically-driven light emitting silicon-based tunnel junction operating at room temperature. We show that such a junction is a source for plasmons driven by the electrical tunnel current. We find that the emission spectrum is not given by the quantum condition where the emission frequency would be proportional to the applied voltage, but the spectrum is determined by the spectral overlap between the energy-dependent tunnel current and the modal dispersion of the plasmon. Experimentally we find the highest light outcoupling efficiency corresponding to the skin-depth of the metallic contact of this metalinsulator-semiconductor junction. Distinct from LEDs, the temporal response of this tunnel source is not governed by nanosecond carrier lifetimes known to semiconductors, but rather by the tunnel event itself and Heisenberg's uncertainty principle.

“…Meanwhile, working engagement provides important personal resources needed in behaving (Salanova, 2008). Kahn (1990) argued that engagement can utilize members of the organization in working roles in which they will use and express themselves physically, cognitively, emotionally, and mentally during performing their roles. M. Bakker, (2006) said that working engagement is characterized by high energy levels and can be identified with one's work.…”

Transformational leadership is one of the leadership types that can be applied in an organization, especially for organizations in the field of education. This study was conducted on several lecturers spread across several campuses in Indonesia. The research method uses SEM- {PLS). The results showed as follows. (1) Engagement influences performance with a T-statistic value of 4.000 (> 1.96). Furthermore, the original sample estimate value is positive that is 0.582. Therefore, H1 is accepted. (2) There is a significant relationship between transformational leadership and engagement with a T-statistic value of 16.737 (> 1.96). Furthermore, the original sample estimate value is positive that is 0.820. Therefore, H2 is accepted. (3) There is no significant relationship between the transformational leadership and performance with a T- statistic value of 0.145 (< 1.96). Furthermore, the original sample estimate value is positive that 0.202 which indicates that the relationship between transformational leadership and performance is negative. Therefore, H3 is rejected.

“…Some of them assume that lecturer's engagement as an emotional and intellectual engagement is for their organization (Saks, 2006). (Kahn, 1990) has defined individual's engagement to take an advantage from the organization member for their role; as in the engagement, people use and express their selves through physic, cognitive, and emotional during the role of the performance. (Schaufeli & Baker, 2004) defines an engagement as a positive mind, satisfying, related to the job that is marked with spirit, dedication, and uptake.…”

This study aimed to measure the effect of perceived organizational support on performance of private higher education lecturers in Tangerang which are mediated by lecturer engagement. Data collection was done by simple random sampling to the private higher education lecturer population in Tangerang. The returned and valid questionnaire results were 231 samples. Data processing was used SEM method with SmartPLS 3.0 software. The results of this study concluded that perceived organizational support have a positive and significant effect on the lecturer performance, both directly and indirectly through mediating lecturer engagement. This new research proposed a model for building the lecturer performance among the private higher education lecturers in Tangerang through enhancing perceived organizational support with lecturer engagement as a mediator. This research could pave the way to improve lecturer readiness in facing the era of education 4.0.
