electroelectronics
The term "electroelectronics" is not a recognized or established field of study or technology in mainstream science or engineering. It appears to be a portmanteau, combining "electro" which relates to electricity, and "electronics," which deals with the control of electric energy and its application. In common usage, the concepts of electricity and electronics are already deeply intertwined. Electricity is the fundamental phenomenon, while electronics is a specialized branch that utilizes electrical circuits and components, often involving semiconductor devices, to process and transmit information.
It is possible that "electroelectronics" might be used informally to describe areas that bridge fundamental electrical
