We have characterized the charge transport properties of the electronic state at the interface between tetrathiofulvalene and 7,7,8,8-tetracyanoquinodimethane organic crystals as a function of pressure. At low temperature and for all studied pressures, the conductance and the current through the interface exhibit a power-law dependence on both temperature and bias voltage which reveal features of quasi-one-dimensional character. The transport behavior as well as the pressure dependence of the power-law exponent is consistent with a one-dimensional Wigner crystal model. Our results demonstrate that organic heterointerfaces can provide an ideal platform for exploring the rich electronic phenomena in low-dimensional systems.
