| Popis: | It has been shown that conjugated polymers possess the two basic requirements for electrically pumped lasers: (1) they can support optically-pumped lasing, and (2) they can support current densities of kA/cm2. However, electrically pumped lasing has not been realised yet. The above-mentioned prerequisites are sufficient when traditional III–V lasers are concerned. However, conjugated polymers are in many ways different and hence require a slightly modified emphasis. We will discuss materials related issues such as charge-induced absorption, charge-mobility, exciton generation, as well as device-related properties such as architecture and driving scheme. |
