What is the unstoppable electrical current that travels down the length of the entire surface of a sarcolemma?

It is called action potential.

Explanation:

Action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
