Findings from University of Ulm Reveals New Findings on General Science (Hybrid sensors based on colour centres in diamond and piezoactive layers)

August 15, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Science have been presented. According to news reporting originating in Ulm, Germany, by NewsRx journalists, research stated, "The ability to measure weak signals such as pressure, force, electric field and temperature with nanoscale devices and high spatial resolution offers a wide range of applications in fundamental and applied sciences. Here we present a proposal for a hybrid device composed of thin film layers of diamond with colour centres and piezoactive elements for the transduction and measurement of physical signals."

The news reporters obtained a quote from the research from the University of Ulm, "The magnetic response of a piezomagnetic layer to an external stress or a stress induced by a signal is shown to affect significantly the spin properties of nitrogen-vacancy centres in diamond. Under ambient conditions, realistic environmental noise and material imperfections, we show that this hybrid device can achieve significant improvements in sensitivity over the pure diamond-based approach in combination with nanometre-scale spatial resolution."

According to the news reporters, the research concluded: "Furthermore, the proposed hybrid architecture offers novel possibilities for engineering strong coherent couplings between nanomechanical oscillator and solid state spin qubits."
