    • Unfortunately, in this work, we did not prepare type-B devices for high-frequency measurements. Thus, we cannot tell whether there is any no-table difference in high-frequency performance between the type A and type B. In general, the emitter-mesa profiles of the type-B devices exhibit outward slant structures. Thus, the emitter contact resistance for the lype B might be somewhat larger than that for the type A. For this reason, one may suspect that the type-B devices should be inferior to the type A in high-frequency performance. However, even if this is the case, this problem can be easily solved by reducing the thickness of cap and emitter layers (and thereby reducing the height of an emitter mesa). In this case, however, it is necessary to use "T-shaped" emitter electrodes (reported in ref. 27) in order to employ a base self-aligned metalization process.
