Room-Temperature Observation of Local and Nonlocal Electronic Quantum States on the Surface of Silicon


Coherent and incoherent stable electronic quantum objects are observed at room temperature due to the formation of regions with the forcefully changed similar charge states on silicon surfaces by atomic force microscopy. Using the theory of entangled states, the interaction conditions for such objects are established and the quantum screening and quantum interference effects between them are explained.
