  1. Characterization and modeling of CdCl2 treated CdTe/CdS thin-film solar cells

    Maxwell, Graham Lane, author, Manivannan, Venkatesan, advisor, Sampath, W. S., committee member, Sites, James R., committee memberColorado State University. Libraries2010

    … promoting CdTe recrystallization, QE response, defect passivation and others. Understanding the effects of the CdCl2 treatment is crucial in order to optimize processing conditions and improve performance. This study investigates the effects of variations of CdCl2 treatment duration on CdTe/CdS …

  2. Luminescent Harnessing of 2D Transition Metal Dichalcogenide Excitons

    Tanoh, AreloUniversity of Cambridge2021

    … is of little practical use. Post-fabrication defect passivation schemes offer a means to recover and enhance optical and electronic properties of newly fabricated monolayers. This thesis presents a novel surface treatment based on oleic acid (OA) ligands, which unlike previously reported …

  3. Reducing Off-State Current in P-Type Metal Oxide Thin Film Transistors

    Meeth, David JakeUniversity of Cambridge2023

    … the more dominant source of the off-current, defect passivation was investigated. A minimum of 5 nm of Al<sub>2</sub>O<sub>3</sub>, when applied as a passivation layer to the back channel of annealed Cu<sub>2</sub>O TFTs, was shown to greatly improve the on/off ratio by 150000 %, three orders …

  4. Electronic structure, defect formation and passivation of 2D materials

    Lu, HaichangUniversity of Cambridge2019

    … carrier mobility. Then we consider the defect formation of 2D HfS2 and SnS2 which are candidates in the n-type part of a tunnel FET. We found that these two materials have high mobility but there are also intrinsic defects including the S vacancy, S interstitial, and Hf/Sn interstitial. …

  5. Control of chiral optical and spin properties in low-dimensional perovskites

    Liu, SunhaoVirginia Tech2026

    … performance of the 3:1 system arises from defect passivation by THFA's N and O atoms, which suppresses EY relaxation, and a lower excitonic binding energy that weakens DP relaxation. These results establish mixed chiral-cation engineering as an effective approach for controlling spin …
