An international team of researchers (USA – Arizona State University, Japan, China, UK) explored the charge transport properties through the molecules. They demonstrated that quantum interference can be precisely modulated in two different configurations of the molecule, known as Para and Meta. It turns out that quantum interference effects can cause substantial variation in the conductance properties of molecule-scale devices. By controlling the quantum interference, the group showed that electrical conductance of a single molecule can be fine-tuned over two orders of magnitude. The research shows that the field of molecular electronics is open to a broad range of innovations – single-molecule devices could potentially act as transistors, wires, rectifiers, switches or logic gates and may find their way into futuristic applications including SQUID, quantum cryptography, and quantum computing…read more.
