Nonvolatile Multilevel Resistive Memory Switching in Amorphous LaGdO3 Thin Films

Currently, the world is interested in developing alternative nonvolatile memory technology, as generally used MOS transistor based semiconductor memory devices are rapidly approaching the zoom limit. Among all new concepts, metal oxide-based resistive random access memory (RRAM) is expected to be a future promising for its simple metal-insulator-metal (MIM) structure, high memory density, It is a nonvolatile memory application. One of the candidates for competition. High running speed, high durability and long holding power.

Nonvolatile memory: Nonvolatile memory seems to be an interesting topic for technology enthusiasts, but it is huge for everyone in the world who is actually using all kinds of technology. As we connect more and more indexes, people need and use more memory. Compared to volatile RAM memory as the main memory, nonvolatile memory (even computer memory that retrieves information after turning it off or on even after turning it on) is problematic due to cost, performance and write durability issues Has been used for secondary storage. . In 2016, significant progress is expected in the development of a new form of nonvolatile memory in the world that wishes to save more data at a lower cost while using less power. This revolutionizes the computing environment, allowing smaller devices to store more data and larger devices to store large amounts of information.

Thin film transistors will be one of the important elements of the electronic revolution. These TFTs can be made of various semiconductor materials that can be deposited in thin layers, such as amorphous silicon, low temperature polycrystalline silicon, organic semiconductors, and carbon nanotubes. Various materials such as ultrathin glass, stainless steel foil and plastic film can be used as TFT flexible substrate. After many experiments, my team concluded that plastic film is very promising. They are robust, resistant to mechanical distortion, are very low cost, and are compatible with new manufacturing processes for manufacturing large sheets of flexible electronic materials, including roll-to-roll manufacturing methods currently under development. In order to print TFT on plastic film, it is necessary to keep processing temperature sufficiently low so that plastic does not change shape.
