摘要:

ZnMnO层的光学性质在低温下生长的原子层沉积和金属有机气相外延进行了讨论,并比较ZnMnS样品所获得的结果。目前的研究结果表明,在ZnO晶格中的Mn离子的二价。强吸收(开始于约2.1 eV)初步与Mn 2+到3+的光电离有关。ZnMnO发射失活的机制进行了讨论,并解释了假设的Mn2+到3+充电后的过程。

英文摘要:

Optical properties of ZnMnO layers grown at low temperature by Atomic Layer Deposition and Metalorganic Vapor Phase Epitaxy are discussed and compared to results obtained for ZnMnS samples. Present results suggest a double valence of Mn ions in ZnO lattice. Strong absorption, with onset at about 2.1 eV, is tentatively related to Mn 2+ to 3+ photoionization. Mechanism of emission deactivation in ZnMnO is discussed and is explained by the processes following the assumed Mn 2+ to 3+ recharging.
