Highly Energy-Efficient Self-Powered Operation 2-D Floating Gate Memories to Establish the Bionic Antennal Nervous System

The 2-dimensional material floating-gate memory with the blocking oxide layer of antiferroelectric materials and combined with nanogenerators is studied in this project to develop a new self-powered 2-dimensional material floating-gate memory for the realization of the target of highly energy-efficient operation. A force will be applied on the nanogenerator to generate the polarized electric field on the floating-gate memory for the program/erase operation, which can be used in bionic antennal nerve system. A new HiPIMS system will be developed to deposit a high-quality TiS2 film and some nanotechnologies will be used to reduce the operation voltages of floating-gate memory and increase the output voltage of nanogenerator. Finally, a prototype of highly energy-efficient bionic antennal nerve system will be realized. The project can be divided into four parts:1. A HiPIMS system with the design of highly efficient sulfur ionization will be developed. A high-speed sulfur gas nozzle design to ionize the sulfur within the chamber directly and react with Ti atoms to reduce the contamination of sulfur on chamber wall is established with the HiPIMS system to generate a high-density plasma and obtain a high-quality TiS2 film for the use as the floating gate of a memory.2. An antiferroelectric enhanced floating-gate memory with low operation voltages will be developed. The metal-doped ZrO2 film with antiferroelectric polarization behaviors is used as the blocking oxide layer to increase the coupling ratio of floating-gate memory and reduce the operation voltages effectively.3. A nanogenerator with high output voltage will be developed. The SrTiO3/TiO2 nanofibers with ferro-, piezo-, and photo-electric properties and KBNNO nanoparticles with ferroelectricity and photovoltaics is doped into P(VDF-TrFE) film as the nanogenerator, which can increase the output voltage through the photonic annealing to operate the floating-gate memory without any extra energy. 4. A highly energy-efficient bionic antennal nerve system will be developed. The floating-gate memory and nanogenerators are integrated to be a new self-powered 2-dimensional material floating-gate memory. A force is applied on the nanogenerator to bionically operate the floating-gate memory, accomplishing the development of highly energy-efficient bionic antennal nerve system.
