摘要:
A localized nanostructure growth apparatus that has a partitioned chamber is provided, where a first partition includes a scanning probe microscope (SPM) and a second partition includes an atomic layer deposition (ALD) chamber, where the first partition is hermetically isolated from the second partition, and at least one SPM probe tip of the SPM is disposed proximal to a sample in the ALD chamber. According to the invention, the hermetic isolation between the chambers prevents precursor vapor from damaging critical microscope components and ensuring that contaminants in the ALD chamber can be minimized.

A method of fabricating quantum confinements is provided. The method includes depositing, using a deposition apparatus, a material layer on a substrate, where the depositing includes irradiating the layer, before a cycle, during a cycle, and/or after a cycle of the deposition to alter nucleation of quantum confinements in the material layer to control a size and/or a shape of the quantum confinements. The quantum confinements can include quantum wells, nanowires, or quantum dots. The irradiation can be in-situ or ex-situ with respect to the deposition apparatus. The irradiation can include irradiation by photons, electrons, or ions. The deposition is can include atomic layer deposition, chemical vapor deposition, MOCVD, molecular beam epitaxy, evaporation, sputtering, or pulsed-laser deposition.

High density energy storage in semiconductor devices is provided. There are two main aspects of the present approach. The first aspect is to provide high density energy storage in semiconductor devices based on formation of a plasma in the semiconductor. The second aspect is to provide high density energy storage based on charge separation in a p-n junction.

摘要:
An analog TV receiver implementation on DSP allows mobile platforms to view analog TV broadcasting on LCD displays. The analog television receiver includes a demodulator for demodulating a received analog television signal, an analog to digital converter for digitizing the demodulated television signal and a digital signal processor for producing display signals from the digitized television signals. The digital signal processor being programmed to search for a horizontal synchronization signal in the television signal, track the horizontal synchronization signal and search for a vertical synchronization signal in the television signal. Next the processor separates a luminance and a pair of chrominance components of the television signal and demodulates the pair of chrominance components. Red, green and blue values are constructed from the demodulated chrominance components and the luminance components. Display signals are produced from the red, green and blue values.
