Abstract An analytical modeling of the recombination current in the base-emitter space charge region of heterojunction bipolar transistors is derived. The recombination rates as functions of distance in the space charge region are calculated for different hase doping concentrations. The relations between the space charge recombination current and the applied voltage have been determined.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
