Transistor is an element of great importance for electronics, being responsible for functions such as signal amplification and switching. In the context of the electronics alternative to silicon, there is a demand for transistors that can be printed, flexible, transparent, organic or obtained by organic precursors and that can be integrated into smart packaging, ornaments or clothing. In …
High values of ultraviolet radiation expose in tropical and subtropical countries, presents a risk to public health, mainly on the possibility of skin cancer. The monitoring of UV radiation exposition by thin, flexible and printable circuits it's a fascinating proposal. This requires low cost materials that can be process by solution. The ZnO is a semiconductor that stands out in this res…
Actually UV sensors are in featured due to the growth of the hole in the ozone layer and the evils that come with increased exposure of this radiation. It's a technological and social interest the production of UV sensors that can be printed, for example, in smart packaging, article of clothes or adornments. In this context, the challenge of the printed electronics is develop UV sensors t…
The search for sustainable alternatives to silicon-based electronics and conventional processes has fostered the investigation of new possibilities for electronic devices, such as transistors based on eco-friendly and abundant nano-scale materials on flexible and conformable substrates. However, devices designed for disposable applications should be easy to recycle and have the lowest pos…
An interesting way to produce an UV sensor is integrating a diode and a transistor. However, if you want to fabricate this circuit without encapsulation, it's necessary use a blocking filter to prevent devices parameters change. Gallium oxide (Ga2O3) is an interesting material due its large bandgap of ~4.9 eV that makes it an ideal candidate for solar-blind devices and deep UV sensor. The…
