Ultra-wide bandgap semiconductor β-Ga₂O₃ is considered to be an ideal material for the fabrication of SBPDs. However, synthetizing β-Ga₂O₃ with high quality factor while simultaneously in situ modulation of electronic and optoelectronic properties to enhance performance has been challenging. Here, pulsed laser deposition (PLD) technology is used to synthesize high-quality β-Ga₂O₃ thin films on a sapphire substrate. The oxygen vacancy engineered β-Ga₂O₃ films can achieve in situ precise control of their surface morphology, optical parameters, and optoelectronic properties by simply adjusting the oxygen pressure. Meanwhile, the optimal thickness of the β-Ga₂O₃ film for the developing high-performance SBPD is ∼221 nm, determined by fitting and analyzing the optical parameters measured by the ellipsometry. Subsequently, the influence of oxygen pressure on the performance of β-Ga₂O₃ SBPD is thoroughly explored, considering the optimization of electrode size and deposition time. When the oxygen pressure is set to 15 Pa, the β-Ga₂O₃-based SBPD achieves highly competitive responsivity (<em>R</em>) and detectivity (<em>D*</em>) at 250 nm, with values of 1080 A·W⁻¹ and 1.4 × 10¹⁶ cm·W⁻¹·Hz^1/2, respectively. Additionally, the noise component of the β-Ga₂O₃ SBPD is further studied to calibrated the traditional device performance results. This work introduces a simple and straightforward approach to in situ tuning of the optoelectronic properties of β-Ga₂O₃, which is important for advancing β-Ga₂O₃ film growth technology and fabricating high-performance photodetectors.</p></div>","PeriodicalId":100893,"journal":{"name":"Materials Today Electronics","volume":"10 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772949424000287/pdfft?md5=9fbc471e969c83d076214df69c5b1132&pid=1-s2.0-S2772949424000287-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, numerous studies have attempted to experimentally and computationally map out the dominant defects in the phase, these include efforts to determine the dominant defect, estimate defect energies, and predict their concentration. The computer coupling of phase diagrams and thermochemistry (CALPHAD) is one of many tools under the auspices of the materials genome initiative (MGI) that enables the rapid design of new functional materials with improved properties. The Defect energy formalism (DEF) with a charged sublattice, an offshoot of the Compound energy formalism (CEF), provides a way to directly include first-principle defect energy calculations into CALPHAD descriptions of solid phases. The introduction of the charge sublattice enables the estimation of the free carrier concentrations in the phase.
