Effect of different a-InGaZnO TFTs channel thickness upon self-heating stress

In this work, Indium-Galium-Zinc-Oxide Thin Film Transistors (IGZO TFTs) with different channel thickness has been compared after self-heating stress (SHS). In previous literatures, self-heating of TFTs has been widely discussed and Joule Heat caused during driving TFTs has been compared with different channel length and width [1]. However, different channel thickness hasn’t been investigated. Although TFTs with a larger channel thickness possess a greater drain current, a less degradation is observed when comparing with small channel thickness structures, demonstrated in Figure 1(a). The ΔVt shift in the transfer characteristics are well described by the stretched-exponential equation. The Eτ value, which is the average effective barrier height for electron transport, is extracted in Figure (b). Results has shown that in the thick IGZO TFTs, the value is almost twice of that in the thin IGZO TFTs. From COMSOL simulations demonstrated in Figure 1(c), in could be noticed that different channel thickness effects the electrical field locating at the gate insulator. Therefore, a model is proposed to explain the degradation difference, illustrated in Figure (4). Please click Additional Files below to see the full abstract

International human rights law and the right to mental health

Purpose: Why did the WHO claim that there is “no health without mental health”? In its reform of the Ministry of Health and Welfare (MOHW), why did the Taiwan government add oral health into the Department of Mental Health? This paper explores normative accounts for the right to health which include physical and mental health as a highest state for everyone. Challenge the government should not excuse for inadequate resource to add oral to Department of mental health. Methods: We apply an analysis of international human rights law and international conventions to justify how mental health is a human right. Results: The right to the highest attainable standard of health is enshrined in the Universal Declaration of Human Rights, the International Covenant on Economic, Social, and Cultural Rights, as well as the constitution of the World Health Organization. A person’s state of health is conceptualized with a holistic perspective. Mental health, by definition and elements, is critical to an individual’s personal dignity, lifestyle, and living condition. Thus, as the fundamental basis of personal development and functioning, physical and mental health are recognized as a human right in international human rights law. The governments need to take responsibilities to build a mental healthy environment to their people. Conclusions: We found that in practice, governments (including Taiwan) often ignore people’s mental health needs when initiating health or welfare policies, especially if mental health is not regarded as a human right by the government. In fact, some governments refuse to honor mental health as a right although it is a legal obligation under international law. We urge Taiwan’s government to return the structure of the MOHW back to include an independent Department of Mental Health. To influence governmental policies, a change is needed in the research community, because researchers and practitioners in mental health and psychiatry still rarely view mental health from an international human rights perspective as well as for all public not disease oriented. We hope to initiate a review of the basic requirements of the right to mental health in terms of its positive, rather than negative, aspects
