The Chung's resistor exhibits negative resistance. When positive voltage is applied, the current flow in negative direction, i.e. the current voltage characteristics is a straight line of negative slope.
Research leader Deborah D. L. Chung says she has created zero resistance ``without cooling and without a superconducting material.'' When combined with other materials with positive resistance, the scientists came up with zero resistance, she says.
Does the positive resistor exhibit heat dissipation? What happened when staggered together in many layers?
