Resistivity of high-tech feature films and computer testing system, test new law

When the test is slightly higher relative humidity and temperature have a certain relationship. If strict control of guillotine the same test conditions, 'the bias may be even smaller. ●. 2Cu-PPN Power Xiang Nang Nang mm pupil img shame stupid Et of certain words in the ceramic substrate prepared by low temperature plasma technology 3 Cu-PPN PPM method combined with a temperature control system for the conductivity = p) a temperature (T ) study the relationship between the amount guillotine 【a1, film thickness measured by the level meter, three samples of different shapes. Table 2 for test results to export part of data processing parameters, Figure 5 in accordance with the Ln ~-I / T relationship between the curves. Seen from Table 2,MAC 180 color eyeshadow, sample shapes, the shape difference between the value of correction factor f significantly when the sample completely rules, such as 3t f value close to the sample 1. The other two 2,59 Table 2j a Cu - PPN samples Lna-1 / T results of the processing parameters Table2Paramo ~ ef5deducedfromthereliti011betwoenLne a 1/rforCu-PPNsamples shape of the sample I} J} table can ------- Bodhisattva ---------- L ----- ---- itl a semicircle L0.6g3l10.99820.13----]------ r ----- T - r ----- a ----- a quasi-semicircle 2l 1o. 59160. g86410.093_--j eleven thousand one hundred and eleven samples 3tl round l0.99610.97320.077 l difference between the larger f values, indicating that the correction function f factor is obvious,mac cosmetics wholesale, difficulties and even if no rules for sample shape, because f the role of the correction factor will not be too large test error, which for some quasi-conduction properties of thin films compared quantitatively determine the bus with sufficient accuracy. Figure sCu-PPN3 samples IFPM method to measure out the Lno-I / T relationship curves Fig5Ln mouth V81/TCtlffVOofcu-PPNthinfilms. Figure 5 shows the range in the 15 ~ 2OO ℃ above; resistivity test samples showed strong regularity, in line with the class of organic semiconducting materials stingy extension of this temperature the amorphous state of the theoretical description of conduction, thereby Description IFPM method visit the pilot study conduction properties of such functional effectiveness of membrane material. Currently exist in the preparation of high-tech research in the field and encountered new functional thin film materials, due to technical limitations and other factors, the sample size and shape is difficult to control, or even peeled off from the substrate, the storm caused by the traditional test 260 theory and technology can not apply more than by this preliminary study results show that, ZFPM method of testing the resistance may well present a new and effective way. t5 Conclusion The improved DC four-probe (Ⅱ Alexandra method can be used for irregularly shaped thin film sample or quantitative measurement of resistivity, with reasonable accuracy by the micro-computer J Pc / XT, intelligent digital form and the corresponding 【/ O , GPIB communication board composed of IFPM four-probe method l automatic test system with high accuracy, better repeatability, the testing process is short,MBT shoes sale, especially for modern functions resistivity measurement of thin film materials and the research process.
