The two-dimensional topological insulator phase has been observed previouslyin single HgTe-based quantum wells with inverted subband ordering. In doublequantum wells (DQWs), coupling between the layers introduces additional degreesof freedom leading to a rich phase picture. By studying local and nonlocalresistance in HgTe-based DQWs, we observe both the gapless semimetal phase andthe topological insulator phase, depending on parameters of the samples andaccording to theoretical predictions. Our work establishes the DQWs as apromising platform for realization of multilayer topological insulators.
