GaAs – your flexible friend! Aligned arrays of GaAs wires with integrated ohmic contacts generated from high‐quality, single‐crystalline wafers via photolithography and anisotropic chemical etching provide a promising class of material for transistors, Schottky diodes, logic gates (see image), and even more complex circuits on flexible plastic substrates. These devices exhibit excellent electronic and mechanical characteristics, which are both important to the emerging area of low‐cost, large‐area flexible electronics, often referred to as macroelectronics.
