This paper presents our in-house fabricated 4H-SiC n-p-n phototransistors. The wafer mapping of the phototransistor on two wafers shows a mean maximum forward current gain (βFmax) of 100 at 25 °C. The phototransistor with the highest βFmax of 113 has been characterized from room temperature to 500 °C. βFmax drops to 51 at 400 °C and remains the same at 500 °C. The photocurrent gain of the phototransistor is 3.9 at 25 °C and increases to 14 at 500 °C under the 365 nm UV light with the optical power of 0.31 mW. The processing of the phototransistor is same to our 4H-SiC-based bipolar integrated circuits, so it is a promising candidate for 4H-SiC opto-electronics on-chip integration.

Due to the high current density in 77K, the high temperature superconducting facilities are expected to improve the efficient in power transmission. Superconducting facilities electromagnetic design is highly dependent on the characteristic of the superconducting tape. As a result, the comparison of the effect of different tape in electromagnetic design should be studied. In this paper, several facilities model are used as example to analyze the effect of different tape utilization. The result shows in different application conditions, or, specific benefits are considered, there is a specific tape will be the best choice.
