Thanks to photocurrent spectral atomic force microscopy (PCS-AFM), researchers at the Massachusetts Institute of Technology (MIT) say they have been able to observe photoactive pixels switching on and off in a heterostructure made of two different 2D materials. The technique might help in the design of new electronic and optoelectronic devices based on these atomically thin structures……
