This course introduces the theory and application of characterization techniques used to examine the atomic structure of materials. Students will learn to classify the structure of materials such as semiconductors, ceramics, and metals according to the principles of crystallography. Characterization methods commonly used in academic and industrial research, including X-ray diffraction and electron microscopy, will be demonstrated along with their application to the analysis of nanostructures. Prerequisites: ENGR 50 or equivalent introductory materials science course.
Fabrication Courses
The first part of the course will consist of a hands-on introduction to the techniques of micro and nanofabrication using Stanford’s shared nanotechnology research facilities, SNF and SNSF, complemented with field trips to local companies and other research centers to illustrate the many applications of nanotechnology, such as DNA microarrays, microfluidic bio-sensors, and microelectromechanical systems (MEMS). The second part involves students proposing, planning, and executing a project “to build something at the nanoscale.” Really, that is the criteria, “build something at the nanoscale.” The professors will of course enthusiastically aid in refining your projects and helping you realize them, but the initial spark will be from your creativity. With access to 10s of millions of dollars of nanotech equipment available to aid in realizing your vision, we hope you accept this challenge with gusto. Examples of recent projects include biosensors using aptamer probes, gecko-inspired dry adhesives, and ultrasensitive strain sensors using diffraction gratings.
Have you ever wondered what is inside your phone and your computer? What physical events happen in between the time you press the “search” button and the information shows up on the screen? What happens after you pressed the key to do a Google search? What are the advances in technology that made that happen? Can some of the same technologies be applied in various fields such as biomedical research and finding solutions to renewable energy?
In this course, we start with the classic paper by Richard Feynman, "There's Plenty of Room at the Bottom," which laid down a challenge to the nanotechnologists. Today’s microchips are nanotechnology in action. Transistors are nanometer scale. We will introduce students to the tools of nanotechnologists and the basic elements of nanoscale science and engineering such as nanotubes, nanowires, nanoparticles, and self-assembly. We will visit nanotechnology laboratories to consolidate our learning, go into the nano@stanford nanofabrication facilities, and do a four-week project on nanofabrication. Hands-on laboratory work will be introduced (e.g., lithography, seeing things at the nanoscale using electron microscopes). We will learn how to build transistors from scratch and test them.
Students will develop an understanding of the scientific basis of nanotechnology and be exposed to nanotechnology from a broader societal perspective. Students will also be exposed to the latest research advances in nanotechnology that may have impact on daily life. Specifically, students will learn how microchips are made. Hands-on laboratory work will be introduced (e.g. lithography, seeing things at the nanoscale using electron microscopes).
Introduction to next-generation techniques in genetic, molecular, biochemical, and cellular engineering. Lab modules build upon current research including: gene and genome engineering via decoupled design and construction of genetic material; component engineering focusing on molecular design and quantitative analysis of experiments; device and system engineering using abstracted genetically encoded objects; and product development based on useful applications of biological technologies.
Second quarter of two-quarter sequence. Experimental aspects of chemical engineering. Emphasizes experimental design, project execution, team organization, and communication skills. Lab section times will not be assigned, though students should expect to spend at least 5 hours per week on average in the lab working on their team research projects. Labs will typically be available M-F between 9am-6pm; to be arranged separately. Prerequisite: CHEMENG 185A. Corequisite: CHEMENG 150.
The underpinnings of modern technology are the transistor (circuits), the capacitor (memory), and the solar cell (energy). EE 116 introduces the physics of their operation, their historical origins (including Nobel prize breakthroughs), and how they can be optimized for future applications. The class covers physical principles of semiconductors, including silicon and new material discoveries, quantum effects, band theory, operating principles, and device equations. Recommended (but not required) co-requisite: EE 65 or equivalent.
From early church architectures through modern housing, windows are passages of energy and matter in the forms of light, sound, and air. By letting in heat during the summer and releasing it in the winter, windows can place huge demands on air conditioning and heating systems, thereby increasing energy consumption and raising greenhouse gas levels in the atmosphere. Latest advances in materials science have enabled precise and on-demand control of electromagnetic radiation through 'smart' dynamic windows with photochromic and electrochromic materials that change color and optical density in response to light radiance and electrical potential. In this course, we will spend the whole quarter on a project to make and characterize dynamic windows based on a representative electrochromic material system, the reversible electroplating of metal alloys. There will be an emphasis in this course on characterization methods such as scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS), optical spectroscopy, four-point probe measurements of conductivity, and electrochemical measurements (cyclic voltammetry).

Enroll in this class to explore the intriguing link between materials science and culinary. Through the lens of the materials science tetrahedron, we will uncover how nano- and micro- structures along with processing techniques shape the textures and appearances of everyday foods. We will delve into the science behind culinary phenomena, like appearances of blooms on aged chocolate, the glossy finish on perfectly tempered chocolate, the icy texture of freezer-burned ice cream, and the crunchy lucky-charm-like texture of marshmallows. With the understanding of materials science, we will examine how your skills in the kitchen can be improved. How, exactly, can you avoid ruining a perfectly soft ice cream with freezer burns? In this course, you will also learn how to describe and analyze edible materials with relevant technical terms. Come with an open mind and a dash of creativity. Let us discover the fascinating science hidden in your kitchen together.
