摘要：
We have fabricated capacitively coupled two quantum wires having a series of quantum dots to study Coulomb drag between the two quantum wires. We have observed strong negative Coulomb drag when the electron transport through the dots is in the tunneling regime for both wires. This indicates that electrons in one dot of the dive wire and holes in the other wire are strongly correlated to generate exciton-like transport.
