Há 5 dias · Electrical engineering and computer sciences professor emeritus Constance Chang-Hasnain (M.S.’84, Ph.D.’87 EECS) has won the IEEE Nick Holonyak Jr. Medal for Semiconductor Optoelectronic Technologies.
Há 1 dia · O dispositivo é capaz de emitir luz de forma eficiente e econômica, portanto é uma alternativa interessante para a iluminação pública e residencial. O primeiro LED foi criado em 1963 pelo engenheiro e inventor estadunidense Nick Holonyak. Na época, o componente só tinha capacidade para emitir luz vermelha. Veja onde acontecerá o ...
Há 1 dia · We investigate ion–electron Coulomb drag in 2D nanofluidic slits using a generic physical model based on the Boltzmann transport formalism. The emphasis is placed on the fluid, oxide, and semiconductor dielectric constants as well as on the geometry and oxide thickness to maximize the electronic drag current and power output. Our model confirms electronic drag current amplification predicted ...
Há 4 dias · The first visible LED was created in 1962 by Nick Holonyak, glowing a faint red. Engineers struggled to create blue LEDs for decades as blue light required a larger band gap. The race to create blue LEDs involved major companies like IBM, GE, and Bell Labs.
Há 2 dias · Fundamentally, yielding a high-contrast signal has been the primary motivation for photo-plasmonics and associated biosensing modalities. In the case of PRISM, this is achieved through two strategies: (1) attenuating the overwhelming background reference light and (2) ameliorating the weak scattered light intensity by interfacial nano-engineering. 1,12 The first approach usually necessitates ...
Há 1 dia · O objetivo do curso é promover o conhecimento sobre as diferentes tecnologias de depilação definitiva, com foco no Holonyak, único aparelho do mundo capaz de realizar a depilação a LED, tecnologia mais avançada para remoção de pelos.
Há 1 dia · As part of a challenge for 2024, I've decided to see how many QRSS signals I could capture on the 28 MHz band during the year. On the 3rd of June, I added M0GBZ and G0FTD to the tally during a short skip Sporadic-E opening at about 16:00 UTC.
