Giant Rashba spin splitting in strained KTaO3 ultrathin films for circular photogalvanic currents

13 Jan 2020 Wu Ning Zhang Xue-Jing Liu Bang-Gui

Strong Rashba effects at surfaces and interfaces have attracted great attention for basic scientific exploration and practical applications. Here, the first-principles investigation shows that giant and tunable Rashba effects can be achieved in KTaO$_3$ (KTO) ultrathin films by applying biaxial stress... (read more)
