title = "Plasmalike negative capacitance in nanocolloids",
abstract = "A negative capacitance has been observed in a nanocolloid between 0.1 and 10-5 Hz. The response is linear over a broad range of conditions. The low- ω dispersions of both the resistance and capacitance are consistent with the free-carrier plasma model, while the transient behavior demonstrates a possible energy storage mechanism. A collective excitation, therefore, is suggested.",
