- 요약Due to the end of Dennard scaling, problems with the Von Neumann bottleneck, and the unique challenges posed by the volume of data generated on the internet neuromorphic computing has emerged an energy efficient computing method. While standard neuromorphic solutions use matrix math to churn through tables of numbers, in the last several years dedicated hardware has emerged that has optimized the overhead these computations incur in digital systems. Research into memristors has emerged as an alternative method to create neuromorphic systems capable of implementations of synaptic inference more closely matching the computations made in the brain than faux digital or analog systems. Instead of a series of amplifiers, transistors, and resistors necessary for digital and analog systems memristive systems can implement a biomimetic computational paradigm within several two terminal devices. In the variety of memristive systems LiNbO2 stands out due to its already proven large change in resistivity, low power programmability, dynamic and static control of resistivity ranges and temporal response, ability to create volatile, non-volatile and even mixed volatility responses and the ability to implement inductive analogues via ionic momentum. In hopes of unlocking the lowest power neuromorphic implementation to date, LiNbO2 has been investigated as a promising class of memristor devices. Prior investigations were limited to optical lithography scale devices yet compared very well to nanoscale devices from other technologies. This thesis explored methods to a) produce suitable LiNbO2 films allowing scaling to nanometer length scales and b) LiNbO2 devices were scaled past optical lithography lengths resulting in state-ofthe-art breakthroughs in power efficiency.CHAPTER 1 focuses on why neuromorphic computing has become a topic of interest and the need for more biomimetic architectures. It shows how a variety of VLSI silicon systems have successfully implemented a more biomimetic style of neuromorphic computing with results that indicate the approach can improve the power use and accuracy of neural nets.CHAPTER 2 introduces the different types of memristors in the field and discusses how these systems change their resistivity. CHAPTER 3 then discusses in depth LiNbO2, the focus of this dissertation. It discusses how this material system can use delithiation as a resistance modulation mechanism that can allow it to change its resistivity by over 4 orders of magnitude, the methods of fabrication and the recent history of the exploration of the memristive properties of LiNbO2. CHAPTER 4 begins the primary body of work of this thesis by discussing Electron Beam Lithography (EBL) and the unique chemistry and materials challenges encountered in scaling LiNbO2 to the nanoscale. CHAPTER 5 demonstrates the devices created using ebeam lithography and uncovers how at the nanoscale these systems may be lithium extraction limited. It also finds that the initial low power programming that sparked this investigation continues to scale down to 150 nm. CHAPTER 6 discusses the experiments performed with LPEE and found that despite a promising lattice match to LiNbO2, SiC may not be a suitable substrate due to chemical reactions with the LPEE environment. However, the discovery of a novel interfacial NbC thin film could warrant further exploration. CHAPTER 7 then concludes this dissertation and discusses how future work could improve LiNbO2 devices. One of the major objectives delivered in this project was the scaling of LiNbO2 devices to the nanoscale to better compare its properties to other state of the art material systems. It is found that scaled LiNbO2 memristors outperform all other published memristors in terms of the crucial sensitivity figure of merit R/V.
