Conference

Modern developments in photonics, quantum electronics, and related aspects of nanoscale science are creating widespread anticipation and excitement for a new field of quantum engineering. However, an impactful engineering discipline needs more than just device physics and fabrication tools. In order to harness quantum phenomena to build robust high-performance technology we will need new methods for designing circuit and network architectures that incorporate coherence, quantum noise and entanglement. This methodology will need to connect high-level algorithmic concepts with low-level physical modeling, and introduce new design abstractions to replace inapplicable classical ones such as the ideal amplifier/buffer. In this talk I will provide a high-level overview of our group's approach to this type of research, highlighting both case studies in quantum circuit design and the development of a broadly useful software package called QHDL.

The Secure Internet of Things Research Program has a weekly research seminar in the winter quarter of 2015. The seminar meets 11AM-Noon on Mondays in Gates 415 and is open to the public. We encourage students who are looking for research topics and ideas to attend. Refreshments (coffee, bagels, etc.) are served. 

Please see the entire schedule on the seminar web page

All IEEE general members and prospective members are invited, to:

• Give feedback on our IEEE chapter's impact, and share ideas for improvement
• Propose new events that you'd like to see happen on campus
• Meet current officers, and learn more about getting involved

Come help us kick off the new year, and make IEEE a more useful resource for the Stanford engineering community!
Light refreshments will be served.

Please RSVP  so that we can get an approximate head count.

Solution-processed semiconductor nanocrystals have attracted great interest in optoelectronics including color conversion and enrichment in quality lighting and display backlighting [1]. In this talk, we will present types of colloidal nanocrystals obtained by tailoring and controlling the composition, size, and dimensionality of these semiconductor nanomaterials in an effort to realize high performance in light generation and lasing [2]. Based on rational designs and control of the excitonic properties in these nanocrystals, we successfully demonstrated efficient light-emitting diodes [3] and lasers [4-5]. These include colloidal quantum dots, quantum rods and quantum wells. We showed that electronic-type tuning in colloidal quantum dots and rods allows for the fine tunability of the spectral position of the amplified spontaneous emission [4]. Ultra-low threshold stimulated emission in the blue to red was achieved using engineered core/shell quantum dots enabling suppressed Auger recombination. We developed an all-colloidal laser using the nanocrystals as optical gain media. Also, we showed that the colloidal quantum wells uniquely combine ultra-low threshold stimulated emission and record high optical gain coefficients; and the excitonic properties of these colloidal quantum wells can further be tuned by controlled stacking [5]. Furthermore, we developed large-area (> 50 ? 50 cm) freestanding sheets of nanocrystals and their integrated macrocrystals towards stable, efficient and quality solid-state lighting [6]. These results indicate that colloidal optoelectronics holds great promise to challenge epitaxial counterparts in the near future.

In this presentation we will give an introduction to imec for students and scientists who are interested in engaging with imec involving activities going from following on-line lectures and seminars to spending a short research stay at imec. Imec was established in 1984 and has since then grown into one of the major players in the field of nanoelectronic research, collaborating with a broad spectrum of industrial partners and universities. Imec is headquartered in Leuven, Belgium, and has offices in Belgium, the Netherlands, Taiwan, US, China, India and Japan. Its staff of over 2,080 people includes more than 670 industrial residents and guest researchers. Imec leverages its scientific knowledge supported by global partnerships in ICT, healthcare and energy. Imec aims to deliver industry-relevant technology solutions. In a unique high-tech environment, and its international top talent is committed to providing the building blocks for a better life in a sustainable society.

Imec offers a stimulating environment to do internships, PhD and postdoc research. The world-class facilities and available expertise guarantee an unmatched support. Within an international atmosphere. In the presentation we will first give a bird's eye overview of the various research programs that are running at imec. Then we will present the possibilities and procedures for PhD and postdoc student exchanges with Stanford university, based on a student exchange agreement that was signed a few years ago. In this agreement Imec is seeking to host PhD students for periods of 3-6 months. They will get the opportunity to work in one of our program teams on topics that can be either related or non-related to their own PhD topic. We will also introduce imec Academy as the imec training and education center which offers a large set of online lectures and seminars in the various expertise fields of imec, which can be followed by Stanford researchers, M. Sc and PhD students. Finally, we will introduce the possibility to apply for scholarships for short stays at imec offered by the Erasmus Mundus Master of Nanoscience and Nanotechnology (for senior researchers) and by the Roger Van Overstraeten Society (for master students). After the presentation we will be available for questions from interested students.

Through decades of scaling the size of computing has gone to virtually zero. In foreseeable future, computing will be all around us, in mostly invisible forms, leading to hundreds of billions of connected computing-devices, sensors, things and people. The future smart connected world relies on energy-efficient computing and communication systems to enable battery operated always on always connected devices. The need for multi-Gbps wireless communication with battery-operated devices and extremely low-power self-sustainable sensor nodes will create an energy-gap that calls for order-of-magnitude energy-efficiency improvements in communication systems. Today's mostly-static wireless systems are designed for worst case channel, process and use case conditions, leading to sub-optimal power consumption when the respective conditions are not at worst case. This talk will highlight the design of context-adaptive zero-margin communication systems that adapt itself to real-time channel conditions, manufactured process-variations and use-cases to always operate with minimum power possible.
