Tailoring macroscopic functionalities in a semiconducting oxide (C09*)

在这个项目中，我们的目标是控制铁磁氧化物半导体EuO中的稳态和暂态功能。将采用两种互补的方法：先进的晶体工程-控制稳态，以及飞秒光激发-控制暂态。先进的工程方法依赖于制备和表征不同横向构型和尺寸的EuO薄膜，以产生外延应变、邻近或量子限制效应。作为下一步，我们将利用时间分辨磁光和光电子能谱来探索飞秒电子和自旋动力学，主要目的是通过先进的晶体工程来操纵稳态中的磁序。

In this project we aim at controlling both the steady and transient functionalities in the ferromagnetic oxide semiconductor EuO. Two complementary approaches will be employed: advanced crystal engineering - to control the steady state, and femtosecond optical excitation - to control the transient state. The advanced engineering approach relies on the preparation and characterization of EuO thin films in different lateral configurations and dimensions to generate epitaxial strain, proximity, or quantum confinement effects. As a following step, we will employ time-resolved magneto-optical and photoemission experiments to explore the femtosecond electron and spin dynamics with the main aim of manipulating the magnetic order in the steady-states induced via advanced crystal engineering.
