Nonlinear emission characteristics of (111)-oriented diamond p–i–n junction light-emitting diodes (LEDs) were investigated. We measured the superlinear increase of excitonic emission and sublinear increase of deep-level emission due to defects an

We have investigated the electrical and light-emitting characteristics of (001)-oriented homoepitaxial diamond p-i-n junction diodes with the boron-doped p-type, non-doped intrinsic, and phosphorus-doped n-type layers formed by applying an optimized

Detailed characteristics of excitonic emission in indirect semiconductors are theoretically examined based on Bose–Einstein statistics and mathematical formulations for the excitonic emission lines are presented. In the calculation of the emission

A systematic study of cathodoluminescence (CL) emission arising from free exciton recombination in diamond is given. CL spectra of free exciton emission from diamond under high excitation conditions were used to characterize properties of ultradense

The influence of nitrogen incorporated in a homoepitaxial diamond thin film on such optical properties such as excitonic emission and optical transition via defect centers was studied in detail by high-resolution cathodoluminescence. It was found tha

For a dilute gas interacting through a short range potential, we have obtained, by starting from the quantum mechanical Hamiltonian, a closed set of evolution equations for the particle distribution and for the expectation values of the four-field-op

We have investigated the electric current through the extended states of quasi 2D substances having linear dimension larger than the collision length. We found that when the Fermi energy just coincides with the single particle energy of the extended

The quasi-2D antiferromagnetic spins interacting with itinerant electrons through the Kondo coupling are investigated to obtain the NMR relaxation rate T 1 -1 . We find that the interlayer spin-spin coupling plays an important role in T 1 -1 at low t
