At present, silicon and gallium nitride, which play a leading role in semiconductor materials, play an important role in different fields. This paper summarizes the characteristics and social application of gallium nitride and silicon and compares them with those of gallium and silicon. Silicon has the characteristics of rich reserves, low price and mature development. Gallium nitride has the characteristics of wide band gap, thermal stability, high frequency, high electron mobility and high power. This study enriches the comparative theory of silicon and gallium nitride. In the process of developing global informatization and economic globalization, it is very important to dig deep into the traditional properties and characteristics of silicon and explore the cutting-edge technology of gallium nitride.","PeriodicalId":259102,"journal":{"name":"Optical Technology, Semiconductor Materials, and Devices","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115667471","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 X-ray powder diffraction were used to analyze the phase formations and purity of Ca3TeO6:xTm3+, xNa+ (0.002 ≤ x ≤ 0.10). The detection wavelength (λem = 454 nm) and a excitation wavenlenth (λex = 359 nm) were used to study photoluminescence spectra. After the comparison of different concentration phosphors, the optimal doping one was found as 0.05. Electric multipole interaction was proposed as the mechanism for concentration quenching in Ca3TeO6 materials. Furthermore, the Ca3TeO6:0.05Tm3+ fluoresces blue with color coordinates (0.161, 0.0671). Based on these results, Ca3TeO6:Tm3+ phosphors could be promising blue-emitting materials for the white light-emitting diodes (w-LED) applications.","PeriodicalId":259102,"journal":{"name":"Optical Technology, Semiconductor Materials, and Devices","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127009838","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 PCF is constructed of multi-layer hexagonal air holes with a silicon core. The inner wall of the two large air holes is coated with gold films for exciting surface plasmon resonances. The transmission characteristics of the fiber are analyzed by the finite-element method. At the wavelength point of 1.55 μm, the confinement losses of the x and y-polarization modes are 1400 dB/m and 15 dB/m, respectively. The severe difference in polarization loss can support the efficient transmission of the y-polarization mode over the range of 1.51-2.24 μm. Only short fiber lengths of 2 cm, the achievable power of the y-polarization mode can be more than 0.5, and the extinction ratio is less than -20dB for the wavelength range. The presented fiber has promising application prospects in polarization-maintaining and high-power laser systems.","PeriodicalId":259102,"journal":{"name":"Optical Technology, Semiconductor Materials, and Devices","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126475454","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}

Therefore, a new cable joint fault detection method is required based on the extended time-frequency domain reflection method. Based on the energy transfer characteristics of the cable, a transmission line schematic is drawn to extract the fault characteristics. Then the fault frequency domain is divided by combining the extended time frequency domain reflection to achieve cable joint fault detection. The experimental results show that the peak values of Wigner-Hough transitions obtained by the designed cable joint fault detection method are less different from the actual ones, which proves that its fault detection effect is good, accurate, and has a certain application value.","PeriodicalId":259102,"journal":{"name":"Optical Technology, Semiconductor Materials, and Devices","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131170152","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}

Using energy storage can reduce the volatility of photovoltaic grid connected power and realize the stabilization of the fluctuation of photovoltaic grid connected power. This paper analyses the requirements of the grid connected power fluctuation rate of the coupling energy storage device of the photovoltaic power generation system and uses the variation modal decomposition to decompose the original photovoltaic power to obtain the grid connected power that meets the fluctuation requirements. An over calculation example verifies that the photovoltaic power can reduce the power fluctuation after being compensated by the hybrid energy storage system and compares and analyses the configuration results of different energy storage schemes, verifying that the method proposed in this paper can reduce the power of energy storage capacity and annual comprehensive cost to improve the economy of the system.","PeriodicalId":259102,"journal":{"name":"Optical Technology, Semiconductor Materials, and Devices","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130834589","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}
