Liquid water based optoelectronic computing chip

Solid-state electronics have revolutionized modern society due to their exceptional computational capabilities. However, the power consumption of chips rises dramatically with increasing integration levels as post-treatment of individual computing unit cost. Here, we introduce a water computing chip with exceptionally low power consumption based on graphene/water/semiconductor photodetectors, which relies on a unique exponential decay of water molecule polarization transfer function (PTF) along ...
