“…It can be seen from the I collect − V driven curve that, I collect becomes measurable when the V driven is larger than ≈3.1 V. It then increases exponentially with V driven and approaches ≈20 µA at V driven = 3.9 V. Taking the horizontally projected area of emitting SACNT films (S = 1500 µm 2 ) into consideration, an emission current density up to ≈1.33 A cm −2 is obtained, which is comparable to that of commercial thermionic electron emitters. [19,20] The driven voltage as a function of emission current density from the device measured in Figure 2b together with those of previously reported gated FEAs [21][22][23][24][25][26] are plotted on the same graph in Figure 2c. Here, driven voltage of FEAs refers to the voltage applied to the gate electrode.…”

An important advancement towards the realization of miniaturized and fully integrated vacuum electronic devices will be the development of on‐chip integrated electron sources with stable and reproducible performances. Here, the fabrication of high‐performance on‐chip thermionic electron micro‐emitter arrays is demonstrated by exploiting suspended super‐aligned carbon nanotube films as thermionic filaments. For single micro‐emitter, an electron emission current up to ≈20 µA and density as high as ≈1.33 A cm−2 are obtained at a low‐driven voltage of 3.9 V. The turn‐on/off time of a single micro‐emitter is measured to be less than 1 µs. Particularly, stable (±1.2% emission current fluctuation for 30 min) and reproducible (±0.2% driven voltage variation over 27 cycles) electron emission have been experimentally observed under a low vacuum of ≈5 × 10−4 Pa. Even under a rough vacuum of ≈10−1 Pa, an impressive reproducibility (±2% driven voltage variation over 20 cycles) is obtained. Moreover, emission performances of micro‐emitter arrays are found to exhibit good uniformity. The outstanding stability, reproducibility, and uniformity of the thermionic electron micro‐emitter arrays imply their promising applications as on‐chip integrated electron sources.

“…In light of this, we are including both developed and developing economies in our research to account for heterogeneous differences in the level of development and institutional development in relation to environmental sustainability and green growth. Secondly, previous studies [25][26][27] focus on carbon emission reduction as an indicator of sustainability. We argue that carbon emissions cannot be generalized as the primary factor in measuring sustainability.…”

Does Ethical Behaviour Affect Sustainable Development? Evidence from Developed and Developing Countries

This paper examines the relationship between ethical behavior and green growth for a large sample of 109 countries, comprised of developed and developing countries. We applied panel corrected the standard error (PCSE) and system generalized moment of method (S-GMM) to achieve the set-aside objectives. We use the recent data from Organisation for Economic Co-operation and Development (OCED). Our results show that high ethical behavior is associated with an increase in green growth, suggesting that the ethical standard plays a significant role in achieving sustainable development. We also find that the relationship between ethical behavior and green growth is more pronounced in developed countries than in developing countries. This is attributed to the ethical standard laid down in most of the developed countries. The results are unaffected by alternative variable measurements and econometric estimations. Our findings highlight the need for policymakers to consider non-economic and technological factors such as ethics to achieve growth that is both environmentally and economically sustainable.
