We present a method for accurately de-embedding the electrical effects of the bias and measurement electrode structure used for spin-torque oscillator (STO) measurements. We propose a simple, but very accurate, method that requires only one additional test structure per STO wafer. We show that the effects of the electrode structure, including phase shift over frequency and insertion loss, can be removed,...
Indium Tin Oxide (ITO) films deposited by magnetron sputtering are widely used as transparent conducting layers for InGaN based light-emitting diodes (LEDs). Compared to ITO films deposited by electron beam evaporation, tthe ITO films deposited by magnetron sputtering typically have higher optical transmittance and greater electrical conductivities, which can result in higher efficiency for LEDs....
A feasible method to extrude Cu-based alloys by a high-temperature melt-extrusion (ME) module and the property characterization of Cu-Zn alloys were conducted. The ME module assembled on 3D Printer (3DP) had different designs from traditional 3DP. The module for 3DP applications has superior characteristics, such as 1100oC-extrusion capability, high heating rate (930 oC/ 5 min), good thermal insulation,...
Based on the screen-printing technology, conductive meshed patterns are printed on a flexible substrate with different loadings. Using empirical formulae, the shielding effectiveness (SE) for the different printed meshed screens is first determined and later verified through experiment. Both the calculated and experimental results demonstrate that reasonably good SE for this type of printed meshed...
