分级透明导电Al：ZnO中形貌驱动的电学和光学性质
Morphology-driven electrical and optical properties in graded hierarchical transparent conducting Al:ZnO
摘要：
采用脉冲激光沉积法制备了不同形貌的Al掺杂ZnO薄膜，研究了Al掺杂ZnO薄膜与功能性能的关系。通过测量所得的表面粗糙度和其对电导率的影响（特别是载流子迁移率，随着粗糙度的增加而显著降低）来监测形态，从而讨论导电机制的局限性。光散射能力的显着变化，由于形态的变化也进行了调查和讨论，研究形态和功能特性之间的相关性。
英文摘要：
Graded Al-doped ZnO layers, constituted by a mesoporous forest like system evolving into a compact transparent conductor, were synthesized by Pulsed Laser Deposition with different morphology to study the correlation with functional properties. Morphology was monitored by measuring the resulting surface roughness and its effects on electrical conductivity (especially carrier mobility, which significantly decreases with increasing roughness) allow to discuss the limitations in conduction mechanisms. Significant changes in light scattering capability due to variations in morphology are also investigated and discussed to study the correlation between morphology and functional properties.
