The performance of plastic semiconductors will be widely used in the electronic field

semiconductors are basic, strategic and cutting-edge industries in the IT field. However, most semiconductors used in the electronic field today are metals. It seems that plastics will always be used in this field in large-size monocrystalline silicon, ultra-high purity metal sputtering targets, optical films, new cobalt materials, rare earth permanent magnet materials Several fields such as high-purity electronic and chemical materials have reached the domestic leading level and cannot match the international advanced level. However, with the continuous progress of science and technology, plastic semiconductors have now become a reality. American scientists recently proposed theories and formulas to improve the electrical properties of plastic semiconductors, which were published in the Journal of the National Academy of Sciences

plastic transistors, also known as organic thin film transistors (OTFT), may be the number one enemy of silicon transistors and become the real killer of destroying this $226billion mature industry that may destroy protective gloves worn in the laboratory. The current semiconductor manufacturing process requires hundreds of steps, and must be carried out in a near vacuum environment with amazing accuracy

sparkowitz, ludwignoriega of the University of California, and Alberto serleo, a professor of materials science and engineering at Stanford University, have created the first theoretical model containing this molecular scale heterogeneous structure, which they hope to understand, predict and improve the conductivity of semiconductor polymers

using this model, researchers found that the conductivity rates of different components of polymer semiconductors are different. They explained that the diversity of this rate depends on whether the components of the polymer are mixed together like a bowl of spaghetti, or if they are bent, they are still as straight as the driveway on the highway. In other words, the entangled structure that enables plastics and other polymers to bend also weakens their conductivity

in the late 1970s, three scientists first discovered that polymers that had previously been considered non-conductive could also conduct electricity under certain circumstances. Therefore, they won the Nobel Prize in chemistry in 2000. Since then, scientists have been hoping to use the rare electrical properties of polymers to create electronic devices that will not break after bending

however, when using polymer semiconductors for experiments, these flexible materials show abnormal transport behavior, that is, the speed of electrons flowing through all parts of the system is not consistent. In this regard, Andrews parkweitz, a professor of chemical engineering at Stanford University and the leader of the latest research, said: plastics or polymers can be well bent or stretched, but on the molecular scale, they are like a bowl of spaghetti. Compared with various silicon and other inorganic semiconductor structures, this structure is more inconsistent. This non-uniform structure has an important impact on the conductive properties of polymer semiconductors

The new model also enables people to better understand how the flexibility and conductivity of polymer semiconductors can be balanced. In addition, researchers have also given a simple algorithm to tell scientists how to control the process of manufacturing polymers, and based on this, design materials with improved electrical properties. The production equipment is independently researched and developed by the company, which also has a trend towards lightness
