Macromolecular carbon structure organic semiconductors come out

According to the report of the American Physicists Organization Network on August 29th, an international scientific research team has for the first time developed an organic semiconductor material containing large molecules, which is structurally stable, has excellent electrical properties, and is inexpensive and can be used for manufacturing. Field-effect transistors are widely used in modern electronic devices. Scientists said that the latest breakthrough will allow plastic-based flexible electronic devices to "blank everywhere." The relevant research was published in the most famous magazine "Advanced Materials" in the field of materials science.

Ona Zucescu, associate professor of physics at Wake Forest University in the United States, and scientists from Stanford University, University of Kentucky, Appalachian State University, and Imperial College London, worked together to develop this. Organic semiconductor materials. Scientists said that the latest research is expected to make artificial skin, smart bandages, flexible displays, smart windshields, wearable electronic devices, and electronic wallpaper into reality.

Scientists pointed out that in the current consumer market, electronic products are very expensive, mainly because televisions, computers and mobile phones and other electronic products are made of silicon, and the manufacturing cost is high; while carbon-based (plastic) organic electronic products are not only manufactured. Convenient, low cost, and light, flexible and flexible, represents the future trend of “electronic devices everywhere”.

Previous studies have shown that the larger the carbon structure, the better its performance. However, scientists have not developed effective methods to produce larger, stable, soluble carbon structures for research until this time the Zucesko team developed this new organic semiconductor material for transistor fabrication. .

Organic semiconductors are plastic materials that have special structures that make them electrically conductive. In modern electronic devices, circuits use transistors to control the current between different regions. Scientists conducted research on new organic semiconductor materials and explored the relationship between their structural and electrical properties.

The Zucescu team also used new materials to create field-effect transistors. This field-effect transistor is a fundamental part of all modern electronic equipment because the performance of the transistor determines the switching speed, details, and other key attributes of the display. Breakthrough is expected to bring tremendous technological advances, and to design an electronic device that is superior in performance and lower in cost and made of plastic.
