　　Flexible solar photovoltaic panels and OLED screens have already appeared. But the materials currently being studied are thinner and more usable. A diode that is only one molecule thick will fundamentally change the technology in the field of optoelectronics. Displays, sensors and solar cells will cost more and have a wider range of applications, and may even be used in clothes in the future.

　　The study was jointly completed by researchers from the Massachusetts Institute of Technology, the Technical University of Vienna, and the University of Washington. The research team mainly studied tungsten diselenide materials. The material is a crystal structure consisting of a single atomic layer of tungsten sandwiched between two layers of selenium. This structure makes tungsten diselenide an extremely durable material even when thinned.

　　Fortunately, the technology used to split graphene also works with tungsten diselenide, so producing this semiconductor diode is not too difficult.

　　A diode is a semiconductor device that allows current to flow in one direction. There are two types of semiconductor materials used for diodes, one is P-type (Positive, positive electrode) and the other is N-type (Negative, negative electrode). Only one of the two can be chosen because the properties of the diode are based on, for example, the germanium or boron atoms doped in the base material. Ultra-thin diodes made of tungsten diselenide do not suffer from the above limitations. These materials can switch between P-type and N-type as needed.

　　Applying this thin film layer to metal electrodes allows the charge state to be controlled entirely electrically. It can also be applied to any surface for folding.

　　This material has broad application prospects and can be used to produce three types of optoelectronic devices (photovoltaic cells, light-emitting diodes and photodetectors).

　　If scientists can perfect tungsten diselenide diodes, countless scientific ideas that are currently impossible to achieve will be realized. Flexible transparent displays will be able to be used in car windshields or smart devices such as glasses and contact lenses. We will usher in the era of cheap flexible solar cell technology. If safety can be ensured, these technologies can even be used on the skin. Who doesn't want a cool arm display device?
