The onset of the COVID-19 pandemic, which began in early 2020, has spawned many industries, especially the automotive and computing worlds. of the chip crisis had made it happen. Even the international rating agency Standard & Poor’s semiconductor crisis. for 2 years He announced that he would continue.

Most major companies predicted that the chip shortage would end this year, in 2022, but Intel CEO Pat Gelsingerthis is the earliest expires in 2023 was thinking. While thoughts on when the chip crisis will end are announced, companies are trying to find solutions to this crisis. Last month, one of the tech giants Samsungfor strategic activities related to next-generation semiconductors and technologies over the next five years 355 billion dollar budget announced that he was leaving. Scientists continue to work on a solution to this problem.

This material is the best semiconductor material ever found

SiliconIt is one of the most abundant elements on Earth and is found in its pure form in many materials such as semiconductor material, computer chips. is the basis of technological material. However, the properties of silicon as a semiconductor are far from ideal. This is largely because silicon adapts very little to the positively charged counterparts of electrons.

This property of silicon, which is insufficient to transport heat, on computers frequent Overheating is one of the main causes of problems. Doing research on different topics MYTHA team of scientists from the University of Houston and other institutions has discovered a material that will eliminate this silicon problem.

cubic boron arsenide This material, called this material, both adapts well to the positively charged counterparts of the electrons and bear the heat extreme Enough found that he stayed. According to the researchers, this material has been found so far best semiconductor material and perhaps the best.

The thermal conductivity of cubic boron arsenite is 10 times greater than that of silicon

in the picture above boron arsenite To date, it has only been tested in lab-scale experiments. As a result of these tests, which the scientists conducted using special methods developed by MIT, this material was determined. heat conduction than that of silicon almost 10 times more discovered that.

The researchers state that more studies are needed to determine whether cubic boron arsenide can be used to replace ubiquitous silicon in a practical, economical way, and claim that they will soon find a number of applications where the material’s unique properties have a significant effect. will make a difference.

The thermal conductivity of the material is very good for any semiconductor, and the scientists also explained that this material has the third best thermal conductivity, after diamond and cubic boron nitride. The researchers explained that even if they discovered the great potential of this material, they didn’t know if and where it would actually be used.

The team explains that they need better materials and more scientists to develop different ways to practically bring this to market, and also wonder whether the necessary funding will be provided to make this work better.
