Deterministic Localization of Strain-induced Single-photon Emitters in Multilayer GaSe
Weijun Luo, Alexander Puretzky, Benjamin Lawrie +7
Nanoscale strain has emerged as a powerful tool for controlling single-photon emitters (SPEs) in atomically thin transition metal dichalcogenides (TMDCs)(1, 2). However, quantum em…
Ultra-low doping and local charge variation in graphene measured by Raman: experiment and simulation
Zhuofa Chen, Nathan Ullberg, Mounika Vutukuru +2
Avoiding charge density variations and impurities in graphene is vital for high-quality graphene-based devices. Here, we demonstrate an optical method using Raman 2D peak-split to…
Monitoring the low doping regime in graphene using Raman 2D peak-splits: Comparison of gated Raman and transport measurements
Zhuofa Chen, Nathan Ullberg, Mounika Vutukuru +2
Avoiding charge density fluctuations and impurities in graphene is vital for high-quality graphene-based devices. Traditional characterization methods require device fabrication an…
Improving Performance of Tin-Doped-Zinc-Oxide Thin-Film Transistors by Optimized Multi-Stacked Active-Layer Structures
Zhuofa Chen, Dedong Han, Xing Zhang +1
In this paper, we investigated the performance of thin-film transistors (TFTs) with different channel configurations including single-active-layer (SAL) Sn-Zn-O (TZO), dual-active-…
