Dr Shu-Jen Wang, who co-led the project with Dr. more than a billion switching operations per second. This new technology is many times faster than previous organic transistors, and for the first time the components have reached operating frequencies in the gigahertz range, i.e.
Crucial to this was the use of highly ordered thin organic layers. Hans Kleemann at the TU Dresden has now succeeded for the first time in demonstrating an organic, highly efficient bipolar transistor. Organic field effect transistors were introduced as early as 1986, but their performance still lags far behind silicon components.Ī research group led by Prof. carbon-based semiconductors, have come into focus in recent years. However, this very rigid technology is less suitable for new types of flexible electronic components, such as rollable TV displays or for medical applications on or even in the body.įor such applications, transistors made of organic, i.e. The increasing performance due to the scaling of silicon electronics in the nanometer range has immensely accelerated the processing of data. First, so-called bipolar transistors were invented, in which negative and positive charge carriers contribute to the current transport, unipolar field effect transistors were only added later. The invention of the transistor in 1947 by Shockley, Bardeen and Brattain at Bell Laboratories ushered in the age of microelectronics and revolutionized our lives. The results of the research work have now been published in the leading specialist journal "Nature". This opens up completely new perspectives for organic electronics - both in data processing and transmission, as well as in medical technology applications. Karl Leo has been thinking about the realization of this component for more than 20 years, now it has become reality: His research group at the Institute for Applied Physics at the TU Dresden has presented the first highly efficient organic bipolar transistor.
