Abstract:
Example embodiments pertain to an organic semiconductor composition, in which low-molecular-weight oligomer compounds are distributed in the spaces of a polymer compound so that the free spaces of the organic semiconductor polymer compound are filled with the low-molecular-weight oligomer compounds upon the formation of an organic semiconductor thin film, thereby increasing π-π stacking effects, and to an organic semiconductor thin film using the same and an organic electronic device employing the thin film. Using the organic semiconductor composition according to example embodiments, a semiconductor thin film and an organic electronic device having improved electrical properties may be manufactured.
Abstract:
An apparatus for storing energy may include: a plurality of nanowire cells electrically connected to each other; and a storage for storing electrical energy generated from the nanowire cells. Each of the plurality of nanowire cells may include: first and second electrodes disposed at an interval; and a nanowire, which is disposed between the first and the second electrodes and made of a piezoelectric material. The plurality of nanowire cells may be electrically connected, so that voltage or current may be increased. Therefore, wireless recharging of the storage connected to the nanowire cells with electrical energy may be enabled.
Abstract:
Provided is a method of manufacturing a ZnO-based thin film transistor (TFT). The method may include forming source and drain electrodes using one or two wet etchings. A tin (Sn) oxide, a fluoride, or a chloride having relatively stable bonding energy against plasma may be included in a channel layer. Because the source and drain electrodes are formed by wet etching, damage to the channel layer and an oxygen vacancy may be prevented or reduced. Because the material having higher bonding energy is distributed in the channel layer, damage to the channel layer occurring when a passivation layer is formed may be prevented or reduced.
Abstract:
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.
Abstract:
Disclosed herein are a method for fabricating an organic thin film transistor, including treating the surfaces of a gate insulating layer and source/drain electrodes with a self-assembled monolayer (SAM)-forming compound through a one-pot reaction, and an organic thin film transistor fabricated by the method. According to example embodiments, the surface-treatment of the gate insulating layer and the source/drain electrodes may be performed in a single vessel through a single process.
Abstract:
A ZnO-based thin film transistor (TFT) is provided herein, as is a method of manufacturing the TFT. The ZnO-based TFT has a channel layer that comprises ZnO and ZnCl, wherein the ZnCl has a higher bonding energy than ZnO with respect to plasma. The ZnCl is formed through the entire channel layer, and specifically is formed in a region near THE surface of the channel layer. Since the ZnCl is strong enough not to be decomposed when exposed to plasma etching gas, an increase in the carrier concentration can be prevented. The distribution of ZnCl in the channel layer, may result from the inclusion of chlorine (Cl) in the plasma gas during the patterning of the channel layer.
Abstract:
Provided may be a Poly-Si thin film transistor (TFT) and a method of manufacturing the same. The Poly-Si TFT may include a first Poly-Si layer on an active layer formed of Poly-Si and doped with a low concentration; and a second Poly-Si layer on the first Poly-Si layer and doped with the same concentration as the first Poly-Si layer or with a higher concentration than the first Poly-Si layer, wherein lightly doped drain (LDD) regions capable of reducing leakage current may be formed in inner end portions of the first Poly-Si layer.
Abstract:
Disclosed is an organic thin film transistor, including a substrate, a gate electrode, a gate insulating layer, an organic semiconductor layer, and source/drain electrodes, in which a fluorine-based polymer thin film is provided between the source/drain electrodes and the organic semiconductor layer. A method of fabricating such an organic thin film transistor is also provided. According to example embodiments, the organic thin film transistor may have increased charge mobility and an Ion/Ioff ratio, due to decreased contact resistance between the source/drain electrodes and the organic semiconductor layer. Moreover, upon the formation of the organic semiconductor layer and insulating film, a wet process may be more easily applied, thus simplifying the fabrication process and decreasing the fabrication cost.
