Abstract for Presentation
The atomic layer deposition in organic Optoelectronics
Atomic layer deposition (ALD) has attracted extensive attention in the field of microelectronics industry and research. Its unique self limiting growth principle can accurately regulate the size and position of the deposited material, and meet the uniformity of growth and the conformability of three-dimensional surface. It is also considered to be the key technology to break through the manufacturing of integrated circuits. Organic optoelectronic devices represented by organic light emitting diode (OLED) have gone out of the laboratory and are gradually produced on a large scale. However, due to the special application requirements such as flexible and transparent, there are still some key scientific and technological problems to be solved, such as thin film encapsulation and transparent electrode. The low-temperature ALD is expected to achieve a breakthrough in the bottleneck problems such as improving the film conductivity, improving the energy level matching, increasing the water vapor barrier and reducing the damage in the fabrication process. Exploring the application of ALD technology in transparent flexible organic electroluminescent devices can not only solve the bottleneck problem of OLED practicality, but also be used in other organic electronic devices, such as organic photovoltaic devices (OPV), Organic thin film transistor (OTFT) devices and other fields play an important role in opening up high-quality film preparation processes that are "friendly" to organic materials, and providing new solutions for the research of transparent and flexible electronic devices.
