Atomically thin p-n junctions with van der Waals heterointerfaces.
Semiconductor p-n junctions are essential building blocks for electronic and optoelectronic devices. In conventional p-n junctions, regions depleted of free charge carriers form on either side of the… Expand
Multi-terminal transport measurements of MoS2 using a van der Waals heterostructure device platform.
Atomically thin two-dimensional semiconductors such as MoS2 hold great promise for electrical, optical and mechanical devices and display novel physical phenomena. However, the electron mobility of… Expand
Force generated by actomyosin contraction builds bridges between adhesive contacts
Extracellular matrices in vivo are heterogeneous structures containing gaps that cells bridge with an actomyosin network. To understand the basis of bridging, we plated cells on surfaces patterned… Expand
