Table 1 Difference between conventional doping and electrical doping

A little amount of interaction is observed between dopant and host atom

There is no chance of interaction between host and dopant atoms

Mismatching of compatibility between foreign atoms and host atoms

No probability of compatibility mismatching as it depends on bias voltage

The exothermic reaction may take place

There is no chance of heat generation. Because heat may destroy molecular thin films

The intermolecular reaction may be observed during this process

No intermolecular reaction takes place
