Strain engineered graphene has been predicted to show many interesting physics and device applications. Here we study biaxial compressive strain in graphene/hexagonal boron nitride heterostructures after thermal cycling to high temperatures likely due to their thermal expansion coefficient mismatch. The appearance of sub-micron self-supporting bubbles(More)
natural increase (births‐deaths). However, Illinois lost 784,988 residents due to net out migration (residents moving out exceeded those moving in). Therefore, the net increase of Illinois residents was 865,940 in the 15‐year time period. • On average, 181,253 people moved into Illinois each year, while 233,583 people moved out of Illinois. As a result,(More)
