    摘要： A three-dimensional (3D) photonic quantum ring (PQR) laser for a low power consumption display, wherein the PQR laser has a sufficient small radius to adjust an inter-mode spacing (IMS) of oscillation modes discretely multi-wavelength-oscillating in an envelope wavelength range within the gain profile of a given semiconductor material of the PQR laser so that the IMS has a maximal value and the number of the oscillation modes is minimized. The PQR laser exhibits multi-wavelength oscillation characteristics according to a 3D toroidal cavity structure, and is designed to exhibit a threshold current lower than those of LEDs and to have multi-wavelength modes in an envelope wavelength range of several nm to several tens of nm. The PQR laser consumes reduced power while maintaining desired color and high brightness equal to those of the LEDs, through an adjustment of the multi-wavelength oscillation characteristics and IMS of the PQR laser.

The particles are admixed in such a fashion as to provide a composite which exhibits a coercivity which behaves as if the coercive particles and the superparamagnetic particles interact. Composites exhibiting such controlled coercivity are useful in the manufacture of transformers, magnets and magnetic tapes.

    摘要： Disclosed herein is a novel process for the manufacture of optical bistable switching device including multiple quantum wells. The process is carried out by: supplying a first organo-metallic compound as the source of a first metallic element and a reaction gas continuously while supplying a second organo-metallic compound as the source of a second metallic element in a discrete mode into a reactor and cultivating a semiconductor multiple quantum wells region having multiple pairs of intrinsic semiconductor-layer/semiconductor-layer(GaAs/AlGaAs), one of the layer containing said second metallic element(Al), while controlling the mole fraction of said second metallic element(Al) to be in the range of 0.01 to 0.25 of the total first and second metal contents existing in the layer containing the second metallic element, thereby lowering the impurity concentration and optimizing the negative resistance.
