One possible strategy for these applications is to harvest energy using the thermogalvanic effect, which converts heat to electricity via an electrochemical reaction. In this work, three device concepts for thermogalvanic harvesting with thin-film Li-ion materials were considered, and a practical experiment demonstrating the operational limitations was presented for each approach.

The first device concept was a thermogalvanic cell. This component harvests energy via the application and removal of a temperature difference between two identical LTO electrodes. In addition, a hybrid Thermally Regenerative Electrochemical Cycling (TREC) device was studied. Here, a cell with an LTO working electrode of variable temperature and a Li metal counter-electrode at constant temperature is charged at one LTO temperature and discharged at another temperature. The last concept was a thin-film TREC cell, which contains an LTO working electrode, a LiPON solid electrolyte, and a Li metal counter-electrode. Harvesting is accomplished by changing the temperature of the entire cell between the charge and discharge steps. By presenting an overview of the advantages and pitfalls of different device concepts, this work is a first step in the development of novel thermogalvanic harvesting components based on thin-film Li-ion materials.","PeriodicalId":100642,"journal":{"name":"IEEE Transactions on Materials for Electron Devices","volume":"1 ","pages":"68-81"},"PeriodicalIF":0.0,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142091008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic integration is a promising way to reduce the footprint of on-chip inductors, which is the main roadblock towards realizing compact RF IC systems-on-a-chip (SoC) operating at GHz and beyond. In the past two decades, researchers have developed many ferromagnetic (FM) or ferrite thin films, laminations, and nanoparticle composites to overcome the frequency limit of the materials, hence, inductors, to GHz range by optimizing materials composition, structure and resistivity, device design, fabrication process, and integration method. The paper starts with reviewing key materials properties required for GHz inductor applications, followed by results of demonstrated magnetic-integrated on-chip inductors. The structural designs of materials and devices, fabrication processes, and the reported device performances of magnetic inductors are summarized. A unique, non-traditional vertical RF inductor with stacked-via magnetic core in CMOS is highlighted.

Among them, a silicon-based 2D material, i.e., silicene, might represent the last frontier of the long shrinking journey of silicon throughout the semiconductor roadmap.
