摘要： A solid state electronic spin system contains electronic spins disposed within a solid state lattice and coupled to an electronic spin bath and a nuclear spin bath, where the electronic spin bath composed of electronic spin impurities and the nuclear spin bath composed of nuclear spin impurities. The concentration of nuclear spin impurities in the nuclear spin bath is controlled to a value chosen so as to allow the nuclear spin impurities to effect a suppression of spin fluctuations and spin decoherence caused by the electronic spin bath. Sensing devices such as magnetic field detectors can exploit such a spin bath suppression effect, by applying optical radiation to the electronic spins for initialization and readout, and applying RF pulses to dynamically decouple the electronic spins from the electronic spin bath and the nuclear spin bath.

摘要： An electron acceleration system includes a first RF cavity, and a second RF cavity whose center is located at a distance not more than 1.5 inch from the center of the first RF cavity, along an axis. The first RF cavity has a length less than about 0.25 inches. The on-axis coupling between the first and second RF cavities along the axis, which is primarily electric, is cancelled out by an off-axis coupling between the RF cavities off the axis, which is primarily magnetic. In this way, the net RF coupling between the RF cavities is zero. The phase and amplitude of the first and second RF cavities are each independently adjustable.

摘要： Phase transition devices may include a functional layer made of functional material that can undergo a change in conductance in response to an external stimulus such as an electric or magnetic or optical field, or heat. The functional material transitions between a conducting state and a non-conducting state, upon application of the external stimulus. A capacitive device may include a functional layer between a top electrode and a bottom electrode, and a dielectric layer between the functional layer and the top electrode. A three terminal phase transition switch may include a functional layer, for example a conductive oxide channel, deposited between a source and a drain, and a gate dielectric layer and a gate electrode deposited on the functional layer. An array of phase transition switches and/or capacitive devices may be formed on a substrate, which may be made of inexpensive flexible material.

摘要： Efficient fluorescence detection is achieved by optically guiding fluorescence light generated by color centers within a sample to photodetectors outside the sample. A fluorescence detection system may use a sample containing one or more fluorescence color centers that emit fluorescent light when irradiated with excitation light from an optical source. The sample has an index of refraction greater than its surrounding medium. The sample may include one or more output faces and further include at least two opposing faces configured to internally reflect the fluorescent light emitted by the fluorescent color centers, and to optically guide the emitted fluorescent light to the one or more output faces. The fluorescence detection system may include one or more optical detector configured to receive fluorescent light emitted through the one or more output faces, and a microwave source configured to manipulate the electronic spin of the fluorescent color centers.

摘要： Reversible phase transitions of exceptional magnitude may be induced in correlated metal oxides by altering their chemical compositions through reversible introduction of dopant ions and electronic carriers into the correlated metal oxides. One or more catalyst electrodes may be deposited onto a surface of a film of a correlated metal oxide such as a perovskite or a transition metal oxide. Dopant ions and electronic carriers may be electrochemically introduced into the catalyst-deposited correlated metal oxide, for example by annealing the catalyst-deposited film of correlated metal oxide in a chamber containing the dopant molecules. In this way, a reversible phase transition of about five to eight orders of magnitude may be induced.

In some embodiments, SE (secondary electron) images of the sample may be acquire, substantially simultaneously with the acquisition of the CL images, so as to generate correlative NP-CL and SE images of the nanoparticle sample. In some embodiments, the nanoparticles may be surface-functionalized so that the nanoparticles selectively bind only to particular structures of interest.

摘要： A photocathode enhancement system includes a cathode plate that is movably positioned relative to an incident optical beam. The emission surface of the cathode plate has an area between about 0.5 cm2 to greater than 100 cm2. The system includes a motion controller that is configured to control the movement of the cathode plate relative to the optical beam, so that the optical beam successively strikes non-overlapping portions of the emission surface, and may reach substantially the entire emission surface over a time period of about 10 seconds to about 100 seconds. The movement of the cathode plate is controlled so that on average, the heat from the optical beam is uniformly distributed over the emission surface of the cathode plate.
