Does base direct current increase or decrease with temperature?

The base direct current (DC) in semiconductor devices generally increases with temperature. As temperature rises, the thermal energy allows more charge carriers to become available, which enhances conductivity and increases current flow. However, excessive temperature can lead to increased resistance and potential device failure, so there is a limit to this trend. In contrast, for some materials, such as metals, resistance typically increases with temperature, which can decrease the current if voltage remains constant.
