Taiwan lacks natural resources and thus sustainability becomes extremely crucial. In order to comply with Taiwan's New Energy Policy, which is to reduce CO₂ emissions (regarded as the main cause of global warming and environmental pollution resulting from burning fossil fuel), green alternative renewable energy must be a top priority. In order to harness the full capacities of …

Oxide materials are gifted systems which have attracted lots of attention over past decades. These materials provide a variety of intriguing functional properties, including superconducting, piezo/ferroelectric, magnetic, high-dielectricity, ferromagnetism, colossal magnetoresistance, transparaent-conducting and etc., where typical examples and configurations are listed in Fig. 1. With …

Online social platforms such as Facebook and Twitter allow users to interact with not only each other, but also a variety of entities via a rich set of social functions. Users can rate items, follow one another, check-in at places, and generate posts with hashtags. Although such heterogeneous social interaction data enrich user experiences and boost the profits of service providers and …

Plant hormones are similar to hormones in animals. They have to be delivered to the proper tissue site through a series of sophisticated transport mechanisms after being synthesized at another tissue site. Then, these plant hormones can function as the signaling molecules to induce the proper physiological response. Therefore, there are a series of active transport proteins that can regulate the …

Continuous global environmental change, leading to extreme rainfall and frequent earthquakes, has played a pivotal role in recent geohazard activities, and the associated landslides and disasters would cause damages directly/indirectly. Notice that extreme events are becoming the new normal, geohazard activities will become more frequent and disruptive. Analyses of landslides under the condition …

By adopting the charge-plasma concept, dopingless FETs with metal-semiconductor (MS) and metal-insulator- semiconductor (MIS) contacts in parallel at the source/drain (SD) have been studied in this work. It is found that currents may be mainly pathing through the MIS contacts for a given SD metal workfunction when the insulator thickness is thin enough. In order to avoid the potential penalty …

In traditional materials, insulators and metals are two entirely different material phases, but the bulk insulating and surface metallic properties are coexistence in topological material (Figure 1). This exotic electronic structure not only display rich fundamental physics but also provide possible applications in next generation electric devices, such as dissipationless spin current and quantum …
