Solid-state color centers with manipulatable spin qubits and telecom-ranged fluorescence are ideal platforms for quantum communications distributed computations. In this work, we coherently control the nitrogen-vacancy (NV) center spins in silicon carbide at room temperature, which telecom-wavelength emission is detected. We increase NV concentration six-fold through optimization of implantation conditions. Hence, coherent achieved temperature coherence time T2 can be reached to around 17.1...
Field emission data from aligned high-density carbon nanotubes (CNTs) with orientations parallel, 45°, and perpendicular to the substrate have been obtained. The large-area uniformly distributed CNTs were synthesized on smooth nickel substrates via dc plasma-assisted hot filament chemical vapor deposition. diameters in range of 100–200 nm employed this study. different obtained by changing angle between electrical field direction. growth mechanism for alignment orientation control has...
Cellulose acetate (CA) is the ester of cellulose produced from via process acetylation. Currently, electrospinning has become a widely used technique to produce CA nanofibers for potential applications such as filtration, medical dressings, and food packaging. Being biodegradable biocompatible, bring additional advantages these applications, e.g., high surface area, porosity, light weight. The quality nanofibers, which can be characterized by prevalence fiber defects, pore size, diameter,...
We presented a high-sensitivity temperature detection using an implanted single nitrogen-vacancy (NV) center array in diamond. The high-order thermal Carr-Purcell-Meiboom-Gill (TCPMG) method was performed on the NV diamond static magnetic field. demonstrated that under small detunings for two driving microwave frequencies, oscillation frequency of induced fluorescence equals approximately average fields. On basis conclusion, zero-field splitting D and corresponding could be determined....

Decent efficiency could achieved when were tuned as normal substrate possible. temperature film thickness...
Defects in silicon carbide have been explored as promising spin systems quantum technologies. However, for practical metrology and communication, it is critical to achieve on-demand single spin-defect generation.
