Multimedia files such as audio and video are often compressed to reduce storage size and to reduce bandwidth consumption during transmission. Moreover these compressed multimedia files will need to be stored in some form of file structure so that the required media data within the file can be retrie.....

有機電致發光器件(OLED)具有優良的發光性能如相應快、亮度高、工作電壓低、因而吸引眾人的注目。現時面積大的OLED，已經被應用於不同的平面顯示器中。OLED的發光機制在於電子和空穴分別從陰陽極注入後，通過在兩電極間的多層有機功能層(空穴注入層HJL，空穴傳輸層HTL，發光層EML，電子傳輸層ETL，電子注入層EJL)在發光分子中結合形成激發子，激子輻射衰變而發光。由於電子和空穴的輸送率一般很難均等，由此造成激發光效率降低。要保持電荷載體的平衡，各功能層的優化是至關重要的。要獲得性能優異的器件，首先要選擇合適的材料。在組成OLED的諸多材料中，有機空穴注入材料的成膜性及其薄膜的熱穩定性和厚 度.....
