Materials Science for III-V/Si Multijunction Solar Cells

Talk Title: Materials Science for III-V/Si Multijunction Solar Cells
Series: Lyman Handy Colloquia
Abstract: Creating a cost-effective, implementable photovoltaic (solar cell) technology is a great and challenging problem for electronic materials research. The premium on utilizing the solar spectrum efficiently is met in importance by the need to do so at low cost and in a manufacturing-friendly, large-scale format. For many years, these often conflicting goals have motivated the desire to integrate high efficiency, III-V compound semiconductor photovoltaics, with their proven high solar energy conversion efficiencies (concentrator multijunction efficiencies exceed 45%), with Si and its existing, low-cost manufacturing industry. There has been tremendous progress toward the creation of Si-based multijunction solar cells in recent years, attributable largely to solving defect issues related to the epitaxial integration of III-V semiconductors (GaAs, GaAsP, GaP)
with group IV substrates (Si, SiGe, Ge). By achieving a defect-controlled III-V/IV heterovalent interface, one can subsequently grow high quality III-V solar cells on top of
the substrate and depending on choice of material, one can also make use of the Si growth substrate itself as a sub-cell within a true III-V/Si multijunction design. This
presentation will focus on our efforts to develop Si-based tandem and triple junction solar cells in which the Si substrate serves a dual use -“ as a low cost growth substrate
and as a high efficiency bottom junction for these unique multijunctions. Indeed this Si-based design also captures the ideal set of bandgaps for maximum efficiency and
therefore has the potential to solve the long-standing conundrum of performance and cost goals for photovoltaics.

Title: Handling Attacker's Preference in Security Domains: Robust and Learning Approaches

Abstract:
Stackelberg security games (SSGs) are now established as a powerful tool in security domains. In order to compute the optimal strategy for the defender in SSG model, the defender needs to know the attacker's preferences over targets so that she can predict how the attacker would react under a certain defender strategy. Uncertainty over attacker preferences may cause the defender to suffer significant losses. Motivated by that, my thesis focuses on addressing uncertainty in attacker preferences using robust and learning approaches.
In security domains with one-shot attack, e.g., counter-terrorism domains, the defender is interested in robust approaches that can provide performance guarantee in the worst case. The first part of my thesis focuses on handling attacker's preference uncertainty with robust approaches in these domains. My work considers a new dimension of preference uncertainty that has not been taken into account in previous literatures: the risk preference uncertainty of the attacker, and propose an algorithm to efficiently compute defender's robust strategy against uncertain risk-aware attackers.
In security domains with repeated attacks, e.g., green security domain of protecting natural resources, the attacker ``attacks'' (illegally extracts natural resources) frequently, so it is possible for the defender to learn attacker's preference from their previous actions and then to use this information to better plan her strategy. The second part of my thesis focuses on learning attacker's preferences in these domains. My thesis models the preferences from two different perspectives: (i) the preference is modeled as payoff and the defender learns the payoffs from attackers' previous actions; (ii) the preference is modeled as a markovian process and the defender learns the markovian process from attackers' previous actions.

2016 Viterbi Lecture

Speaker: Norman Abramson, Professor Emeritus / University of Hawaii
Talk Title: ALOHA to the Web
Series: Viterbi Lecture
Abstract: Wireless access to the Internet today is provided predominantly by random access ALOHA channels connecting a wide variety of user devices. ALOHA channels were first analyzed, implemented and demonstrated in the ALOHA network at the University of Hawaii in June, 1971. Information Theory has provided a constant guide for the design of more efficient channels and network architectures for ALOHA access to the web.
In this talk we examine the architecture of networks using ALOHA channels and the statistics of traffic within these channels. That traffic is composed of user and app oriented information augmented by protocol information inserted for the benefit of network operation. A simple application of basic Information Theory can provide a surprising guide to the amount of protocol information required for typical web applications.
We contrast this theoretical guide of the amount of protocol information required with measurements of protocol generated information taken on real network traffic. Wireless access to the web is not as efficient as you might guess.
Biography: Norman Abramson received an A.B. in physics from Harvard College in 1953, an M.A. in physics from UCLA in 1955, and a Ph.D. in Electrical Engineering from Stanford in 1958.
He was an assistant professor and associate professor of electrical engineering at Stanford from 1958 to 1965. From 1967 to 1995 he was Professor of Electrical Engineering, Professor of Information and Computer Science, Chairman of the Department of Information and Computer Science, and Director of the ALOHA System at the University of Hawaii in Honolulu. He is now Professor Emeritus of Electrical Engineering at the University of Hawaii. He has held visiting appointments at Berkeley (1965), Harvard (1966) and MIT (1980).
Abramson is the recipient of several major awards for his work on random access channels and the ALOHA Network, the first wireless data network. The ALOHA Network went into operation in Hawaii in June, 1971. Among these awards are the Eduard Rhein Foundation Technology Award (Munich, 2000), the IEEE Alexander Graham Bell Medal (Philadelphia, 2007) and the NEC C&C Foundation Award (Tokyo, 2011).
