摘要： Provided are quantum dots having a gradual composition gradient shell structure which have an improvedluminous efficiency and optical stability, and a method of manufacturing the quantum dots in a short amount of time at low cost. In the method, the quantum dots can be manufactured in a short amount of time at low cost using a reactivity difference between semiconductor precursors, unlike in uneconomical and inefficient conventional methods where shells areformed after forming cores and performing cleaning and redispersion processes. Also, formation of the cores is followed by formation of shells having a composition gradient. Thus, even if the shells are formed to a large thickness, the lattice mismatch between cores and shells is relieved. Furthermore, on the basis of the funneling concept, electrons and holes generated in the shells are transferred to the cores to emit light, thereby obtaining a high luminous efficiency of 80% or more. The quantum dot structure is not limited to Group II-IV semiconductor quantum dots but can be applied to other semiconductors quantum dots, such as Group III-V semiconductors quantum dots and Group IV-IV semiconductors quantum dots. Also, the manufacturing method can be utilized in the development of semiconductor quantum dots having different physical properties, and in various other fields.
摘要翻译：提供了具有提高的发光效率和光学稳定性的逐渐组成梯度壳结构的量子点以及以低成本在短时间内制造量子点的方法。在该方法中，可以使用半导体前体之间的反应性差异以低成本在短时间内制造量子点，这不同于在形成核心并执行清洁和再分散工艺之后形成壳体的不经济和低效的常规方法。此外，芯的形成之后是形成具有组成梯度的壳。因此，即使壳体形成较大的厚度，也可以减轻芯部和壳体之间的晶格失配。此外，在漏斗观念的基础上，将壳中产生的电子和空穴转移到核发光，从而获得80％以上的高发光效率。量子点结构不限于II-IV族半导体量子点，而是可以应用于其他半导体量子点，例如III-V族半导体量子点和IV-IV族半导体量子点。此外，制造方法可以用于开发具有不同物理性质的半导体量子点以及各种其它领域。

摘要： A signal sampler and method for high-speed input sampling of a signal are disclosed. A first sampler samples a data signal at a rising edge of a clock signal and generates a first sampled signal. A second sampler samples the data signal at a falling edge of an inverted clock signal and generates a second sampled signal. The first and second sampled signals may be combined to determine the next signal sampler output. An evaluation may include asserting the output signal if the first and second sampled signals are asserted, negating the output signal if the first and second sampled signal are negated, and toggling the output signal if the first and second sampled signals are in opposite logic states. The signal sampler and method of signal sampling may be incorporated in a semiconductor device, which may be fabricated on a semiconductor wafer and included in an electronic system.

摘要： A delay-lock loop includes several delay lines, all but the first of which is composed of at least one variable delay unit that provides a fixed delay and a variable delay. The first delay line is composed of a plurality of fixed delay units, but no variable delay units. The remaining delay lines are each composed of different numbers of variable delay units to provide respective clock signals having different phases, but they do not include any of the fixed delay units. The first and a last delay line receive an input clock signal. Each of the remaining delay lines are coupled to an output of one of the fixed delay units depending on the number of variable delay units in the delay line so that the resulting clock signals have all been delayed the same number of fixed delay periods.

A data order adjuster may re-order the plurality of expansion signals to a predetermined order. A timing generator samples a command signal with an internal clock in a second timing domain to generate a re-timing strobe. The re-timing strobe may be temporally positioned to be within the expansion data window and used to sample the plurality of expansion signals in the second timing domain.
