Figure 1 (IMAGE) Institute for Basic Science Caption Hybrid system formed by combining Bose-Einstein condensate (BEC) and 2D electron gas (2DEG) in novel 2D materials, such as MoS2. Electrons (black spheres) move in 2D electron gas (2DEG, upper layer), and interact with other particles present in the lower layers, where photo-excited electrons and holes (gray spheres, h.) form bound electron-hole pairs. The red wiggly lines represent Coulomb forces acting between particles with opposite charges. Credit IBS Usage Restrictions Please indicate the credit.
