Results for MATSCI

This seminar will explore where we find metals in science and technology today. Starting with the blacksmiths and metallurgists of ancient history, we will introduce the scientific innovations that have enabled today's technology. We will then explore how today's technology uses metals in new and innovative ways - far beyond the metallurgy of old. Students will learn how metals in their bodies can be used for diagnostics and treatments, how metals in geology can show us how planets form, how new metallic tools allow us to 3D print aircraft engines, and more! This will introduce students to the science of metals and explore the career paths that can follow from these technologies.

Independent study in materials science under supervision of a faculty member.

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.

Materials science and engineering for electronic device applications. Kinetic molecular theory and thermally activated processes; band structure; electrical conductivity of metals and semiconductors; intrinsic and extrinsic semiconductors; elementary p-n junction theory; operating principles of light emitting diodes, solar cells, thermoelectric coolers, and transistors. Semiconductor processing including crystal growth, ion implantation, thin film deposition, etching, lithography, and nanomaterials synthesis.

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).

Experimental x-ray diffraction techniques for microstructural analysis of materials, emphasizing powder and single-crystal techniques. Diffraction from epitaxial and polycrystalline thin films, multilayers, and amorphorous materials using medium and high resolution configurations. Determination of phase purity, crystallinity, relaxation, stress, and texture in the materials. Advanced experimental x-ray diffraction techniques: reciprocal lattice mapping, reflectivity, and grazing incidence diffraction. Enrollment limited to 20. Undergraduates register for 162 for 4 units; graduates register for 172 for 3 units. Prerequisites: MATSCI 143 or equivalent course in materials characterization.

Diffusion and phase transformations in materials. Diffusion topics: Fick's laws, atomic theory of diffusion, the generalized flux equations, diffusion in a chemical potential and mass advection. Phase transformation topics: nucleation, growth, spinodal decomposition and interface phenomena. Material builds on the mathematical, thermodynamic, and statistical mechanical foundations of undergraduate physical chemistry and of the prerequisite. Prerequisites: MATSCI 181/211. Undergraduates register for 182 for 4 units; Graduates register for 212 for 3 units. Please sign up for Discussion section 182-Section 02 or 212-Section 02.

Quantum mechanics occupies a very unusual place among theories: it contains classical mechanics as a limiting case, yet at the same time it requires its own formulation. This course serves as an entry to the foundations of quantum mechanics that are relevant to the properties of materials. We build up our foundation of quantum mechanics from simple principles, and then apply them to understanding of atoms and the periodic table. From there then put atoms together in arrangements in solids and investigate how materials properties may emerge. Along the way we will encounter modern applications of quantum mechanics relating to scattering, measurement theory, and quantum information processing.

The elementary principals of x-ray, vibrational, and electron waves in solids. Basic wave behavior including Fourier analysis, interference, diffraction, and polarization. Examples of wave systems, including electromagnetic waves from Maxwell's equations. Diffracted intensity in reciprocal space and experimental techniques such as electron and x-ray diffraction. Lattice vibrations in solids, including vibrational modes, dispersion relationship, density of states, and thermal properties. Free electron model. Basic quantum mechanics and statistical mechanics including Fermi-Dirac and Bose-Einstein statistics. Prerequisite: MATSCI 193/203 or consent of instructor. Undergraduates register for 195 for 4 units; graduates register for 205 for 3 units.

Educational opportunities in high-technology research and development labs in industry. Qualified graduate students engage in internship work and integrate that work into their academic program. Following the internship, students complete a research report outlining their work activity, problems investigated, key results, and any follow-on projects they expect to perform. Student is responsible for arranging own employment. See department student services manager before enrolling.nn*If you do not see your faculty's name listed, please email msestudentservices@stanford.edu the faculty name and the quarter you plan to take the course.
