Latest Patents

De Song's latest patents include an organic semiconductor crystalline film and a method for preparing the same, as well as an organic transistor and organic phototransistor. The organic semiconductor crystalline film is designed to be either an n-type or p-type semiconductor. The organic semiconductor crystal molecules within this film are oriented in a stand-up manner on an ordered substrate, establishing a strong oriented relationship with it. This innovative film is particularly useful for organic transistor and organic phototransistor devices. The preparation method allows for control over the high carrier mobility direction of organic semiconductor crystals, enhancing contacts between crystals and improving the mechanical strength and micro-machining properties of the film. The carrier mobility of the weak oriented epitaxially grown film reaches 0.32 cm/Vs, which is five times greater than that of a vapor phase deposited film and comparable to that of single crystal materials. This invention is adaptable to both glass and plastic substrates.

Another significant patent involves the use of an axial substituted phthalocyanine compound as a semiconductor layer in organic thin-film transistors. The center ligand of this compound features an atom with three or more valences, while the axial ligands can include chlorine, fluorine, or oxygen. This allows for the preparation of high-quality crystalline films on organic substrates using a vapor deposition process. These films exhibit high carrier mobility, a rich energy level, and stable performance, making them suitable for integrated processes. The field effect mobility and the on/off ratio of the organic thin-film transistor exceed 0.01 cm/Vs and 10, respectively.
