摘要:
A compound containing at least two pyridinium derivatives in its molecular structure and being in a reduced form thereof may be used as a CNT n-doping material. The compound may donate electrons spontaneously to CNTs to n-dope the CNTs, while being oxidized into its stable state. An n-doped CNT that is doped with the CNT n-doping material may maintain a stable n-doped state for a long time without being dedoped even in the air and/or water. Further, the n-doped state may be easily controlled when using the CNT n-doping material.

摘要:
An apparatus for generating electrical energy including a first electrode, a second electrode and one or more nanowires, and a method for manufacturing the apparatus for generating electrical energy. The second electrode may have a concave portion and a convex portion. The first electrode and the nanowire are formed of different materials. The nanowire is formed on the first electrode and is positioned between the first electrode and the second electrode. Because the nanowire is formed on the first electrode, the nanowire may be grown vertically and the uniformity and conductivity of the nanowires may be improved. When a stress is applied to the first electrode or the second electrode, the nanowire is deformed and an electric current is generated from the nanowire due to a piezoelectric effect of the nanowire and a Schottky contact between the nanowire and the electrode which makes contact with the nanowire. Accordingly, when the apparatus for generating electrical energy is bent or pressed in part, electrical energy is generated in response to the applied stress.

Exemplary embodiments relate to an energy converting apparatus and a method for converting energy, which may convert energy of an applied signal into electrical energy. The energy converting apparatus may include at least one nanowire which resonates in response to the applied signal. The resonating nanowire may contact an electrode allowing a current to flow through the electrode and the nanowire by a Schottky contact between the electrode and the nanowire. The method for converting energy may include applying a signal to at least one nanowire to resonate the nanowire, and generating electrical energy through the contact between the resonating nanowire and an electrode.
摘要:
A CNT transparent electrode may have a CNT layer consisting essentially of CNT only, together with a cover layer that may include conductive particles and a polymer. The cover layer may cover an upper and/or a lower portion of the CNT layer. The CNT transparent electrode including the CNT layer which essentially consists of CNT only and does not contain other materials such as a binder or a dispersing agent can exhibit excellent conductivity. When the CNT layer is covered by the cover layer, surface roughness, film uniformity, adhesion between the CNT transparent electrode and the substrate and stability in the process of applying the CNT transparent electrode to devices can be enhanced, compared to the case where only the CNT layer is used.

This invention contains the electronic control unit as well as the first accelerator pedal sensor and the second accelerator pedal sensor which are connected to the above-said electronic control unit and whose signal outputs vary according to the angle of the accelerator of the vehicle. The above said first accelerator pedal sensor is supplied with power from the electronic control unit through a first input power supply, and divide the voltage at the first variable resistor into the first output signal and the first source power (0V). On the other hand, the second accelerator pedal sensor is supplied the power from the above-said electronic control unit through the second input power supply, and divide the voltage at the second variable resistor into the second output signal and the second source power (0 V).
