Basically, the saturation can be attributed to a substrate effect characterized by a resistance or a space charge effect featured with a reduced surface electric field. In this work, a self-consistent model based on the particle-in-cell method coupled with a circuit modeling is employed to study the saturation of field emission due to these two effects in order to understand the electrical properties influenced and different characteristics caused.","PeriodicalId":346266,"journal":{"name":"2023 IEEE 36th International Vacuum Nanoelectronics Conference (IVNC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131312816","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}

The probe electrodes have a 0.5 mm by 0.5 mm cross-section and were additively manufactured in stainless steel (SS) via binder material jetting, while the sensor housing was 3D-printed in the glass-ceramic material, vitrolite, via vat polymerization. The 3D-printed MLP was tested in a laboratory helicon plasma. The single and dual LPs showed excellent agreement, to within <5% for all plasma characteristics. The triple LP measured plasma parameters instantly, providing a time-sensitive snapshot of the plasma.","PeriodicalId":346266,"journal":{"name":"2023 IEEE 36th International Vacuum Nanoelectronics Conference (IVNC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126567692","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}

Scattering within the oxide layer limits electron emission but can be counteracted by generating hot-electrons through optical excitation in the underlying semiconductor[2]. Still, the scattering in the oxide persists, limiting the current emission efficiency. Additionally, trapping of electrons causes broadening of the emitted electron energy spectrum. A novel graphene-vacuum-semiconductor (GVS) structure is developed. By eliminating the oxide layer, the tunneling mechanisms can be reduced to Fowler-Nordheim exclusively. As a result, emitted electrons will have an energy spread limited by that of the semiconductor and scattering in the graphene[2]. Additionally, electron trapping in the oxide is eliminated. Field-emission is also increased as the electric field increased by controllably reducing the height of the vacuum gap. Here we will explore the fabrication of vacuum hot electron light assisted cathodes (VHELACs).","PeriodicalId":346266,"journal":{"name":"2023 IEEE 36th International Vacuum Nanoelectronics Conference (IVNC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134504384","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}

The establishment of a complete, locally designed and developed cathodic arc system for the growth of amorphous and nanocarbon films at room temperature was the first significant result. The equipment includes provisions for the growth such as varying deposition ion energies, gas environments, throw distances, and various partial pressures of gas compositions, as well as arc voltage and arc current. This is one of the first indigenous system with provision for the growth of nanocarbons over 200 mm diameter substrates, which can be used to produce a range of high temperature grown materials at low temperatures with the same properties. The systematic work was carried out to demonstrate the feasibility of patterning or creation of periodic metal nanostructures using Nano Sphere Lithography, without masks over large areas at a sub optimal cost. This led to the creation of flat metal triangular pattern of area 0.03 square microns. This was used as a template to grow enhanced electron for the development of periodic metal nanostructures, as a base for the deposition of room temperature nanocarbon on patterned substrates for a wide range of applications including field emitters.","PeriodicalId":346266,"journal":{"name":"2023 IEEE 36th International Vacuum Nanoelectronics Conference (IVNC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126645888","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}
