Electrical impact characterization

This paper reports on the design and characterization of 6.5kV class 4H-SiC PiN diodes with different active areas of 2, 8, and 24mm2 . Diodes edge termination is a combination of MESA and JTE. The blocking voltage of 6.5kV was achieved on the three types of diodes. Diodes operation stability is studied in term of temperature dependence and DC stress. In the limit of used package, these diodes present a stable operation until 225°C. The reverse leakage current at 225°C is less than 3µA at 3kV for 24mm2diodes.

That is not to say that we have to formally plan everything, and keep track of everything we do, and be emotionally shut down. It means that when we are doing whatever we do, we can be aware of our intention and our objectives. We can be aware of why we have our intentions and objectives, of the beliefs that lie behind them. We can be aware of the impact of our actions on achieving what we want to achieve and on the people and things around us. We can be aware of the limited degree to which...

But there is another potential impact for the environment and nature conservation which is a much more positive one. The 1999 structural fund regulations for the first time recognised that the funds could be used for the protection and improvement of the environment (emphasis added). This change in wording was extremely significant – for the first time the doors were open to local and regional authorities and national governments to start putting forward environmental and nature programme proposals which meet the European Union’s cohesion policy objectives set out in the Treaty.
