With the rapid increase in the number of deaths worldwide due to blood related diseases such as malaria, sickle cell anemia and other types of anemias, the importance of more insightful studies on healthy red blood cell (RBC) membrane cannot be overemphasized since the development and progression of these infectious diseases are closely related to the state of the membrane. Furthermore, due to the...
In this paper, we present a low noise integrated heterodyne receiver at 2.7 THz. This heterodyne receiver is based on a superconducting hot electron bolometer (HEB) mixer and a low power consumption quantum cascade laser (QCL) that are both integrated on the same 4 K stage of a pulse tube cooler. We measured the noise temperature of the HEB/QCL integrated heterodyne receiver by using hot and cold...
Millimeter wave detector is an important part of the direct detection receiver[1]. In this paper, a W-band high performance detector circuit utilizing the commercially zero bias diode [2](ZBD) from Virginia Diodes, Inc(VDI) is proposed here. As the datasheet doesn't provide us enough information of the diode, at first we did the parameter extraction from the measured I_V curve to get the series resistance...
3D integration requires vertical stacking of dies while forming permanent electrical and mechanical connections between the input/output pins of the devices. Through silicon via (TSV) is one of the key elements for 3D integration. This paper presents different liner and barrier/seed approaches for realizing 10×100 um void-free copper filled TSVs. Mechanical and electrical performances of these liner...
By adopting HTS tapes in the field winding, the hybrid HTS generator has the characteristics of high power density, high efficiency, low synchronous inductance, etc[1-3]. It is one of the most promising generators in the industry of wind power generation. Damping and screening system (DSS) is one of the key structures in this kind of generator. In order to achieve a better performance, the single...
The electronic band structures and optical gains of Ge/SixSnyGe1−x−y truncated pyramid-shaped quantum dots (QDs) are calculated using the 8-band k.p model. The large bowing factors in the calculation of band gaps of both Ã-conduction and L-conduction valley in the barrier are considered so that the band gaps of the barrier are small. The strains are calculated by constant strain method and valence...
