Imaging and Analysis Center Partners with Industry and Other Institutions

Facilities, Industry

The Imaging and Analysis Center (IAC) supported by PCCM is a world-leading facility for materials characterization. It is a critical resource to our industrial user community. The advanced instrumentation and expertise in the IAC provide ultimate opportunity for us to actively interact with industrial scientists.

New Color Centers in Diamond for Quantum Information Science

Research

Color centers in diamond are a promising platform for quantum information science, as they can serve as solid state quantum bits with efficient optical transitions.

Electrical Manipulation of Nuclear Spins in Silicon

Research

The spin degree of freedom for donor nuclei in silicon have exceptionally long coherence times making them useful as either quantum bits (qubits) or long-lived quantum memories. Nuclear spins are hard to control in nanoscale devices since they are thought to only be coherently manipulated using magnetic fields, which are hard to confine.

Direct Measurement of the Local Glass Transition in Nanophase Structured Copolymers with One Nanometer Resolution

Research

Block copolymers, which self-assemble into nanostructures due to the incompatibility of each block, have generated intense scientific interest and are used in a myriad of important technologies.  In such systems, the majority of the macromolecules can lie within a few nanometers of an internal interface, within a region where the dynamics and mechanical properties can be highly modified from th

Dramatic Tunability in Melting Temperature and Crystallinity of Polyethylene by Exploiting Confinement During Processing

Research

We exploited Matrix Assited Pulsed Laser Evaporation (MAPLE) to deposit polyethylene from a quasi-vapor phase at a controlled substrate temperature, to crystallize polymers under confinement at a wide range of target crystallization temperature, Tc.  The team showed the remarkable controllability of the semi-crystalline structure of PE by MAPLE with the control of substrate temp.; see Figure A

Real-space imaging of a nematic quantum liquid

Research

Interactions among electrons can give rise to a variety of exotic quantum phases in solids. An intriguing example is the formation of “nematic” electronic states, whose wave functions break the rotational symmetry of the host material.

Chiral anomaly observed as an axial current in two topological quantum materials

Research

Electrons in topological materials behave like massless particles (called Weyl fermions). They are either right- or left-handed (the spins are locked parallel or antiparallel to their velocity). In parallel applied electric and magnetic fields, one population grows while the other shrinks. This leads to a new kind of electrical current called an “axial” current.
