Al nanoparticles (NPs) are incorporated in the active layers to enhance the performance of organic solar cells (OSCs).The improved short circuit current Jsc and
Si-based ridge-waveguides with Bragg reflectors are fabricated based on our method.Three resonant peaks could be obviously identified from the photoluminescence
The resonance vibrations of acoustic sensors with two layers of (1120) textured hexagonal piezoelectric films are studied.When the acoustic and electric fields
The energy band structure and current density of electron gas with an exchange-correlation effect in periodic quantum wells are discussed.It is found that the e
