This motif has been used in art and architecture for millennia. Over the past 15 years, materials physicists have used a similar strategy to realize new material properties. In one implementation, two material monolayers with a hexagonal atomic lattice are overlaid with an angle between the two lattices, resulting in an additional long-range lattice structure known as a moir\u00e9 pattern. In 2021, scientists observed the so-called quantum anomalous Hall (QAH) effect in such a twisted bilayer, formed of MoTe<sub>2<\/sub> and WSe<sub>2<\/sub> monolayers [1]. Now Zui Tao at Cornell University and colleagues have used optical spectroscopy to study the interaction between these two monolayers when they are in the QAH state [2].<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The unexpected observation of an aligned spin polarization in certain twisted semiconductor bilayers calls for improved models of these systems.
