TEM Mill
A state-of-the-art ion milling and polishing system offering reliable, high performance specimen preparation. It is compact, precise, and consistently produces high-quality transmission electron microscopy specimens with large electron transparent areas from a wide variety of materials.
For many of today’s advanced materials, analysis by TEM is the best technique for studying material structure and properties. The TEM Mill is an excellent tool for creating the thin, electron transparent specimens needed for TEM imaging and analysis. Ion milling with low angles of incidence, combined with low-energy ion source operation, minimizes irradiation damage and specimen heating.
Because it facilitates the uniform thinning of dissimilar materials, low-angle milling is highly beneficial when preparing layered or composite materials, as well as cross-sectional TEM (XTEM) specimens.

Characterization of small-scale surface topography using transmission electron microscopy
Multi-scale surface topography is critical to surface function, yet the very smallest scales of topography are not accessible with conventional measurement techniques. Here we demonstrate two separate approaches for measuring small-scale topography in a transmission electron microscope (TEM). The first technique...
Entropy engineering of SnTe: Multi-principal-element alloying leading to ultralow lattice thermal conductivity and state-of-the-art ...
The core effects of high entropy alloys distinguish high entropy alloying from ordinary multielement doping, allowing for a synergy of band structure and microstructure engineering. Here, a systematic synthesis, structural, theoretical, and thermoelectric study of multi-principal-element-alloyed SnTe is reported.
Intrinsically low thermal conductivity in BiSbSe3: A promising thermoelectric material with multiple conduction bands
Bi2Se3, as a Te-free alternative of room-temperature state-of-the-art thermoelectric (TE) Bi2Te3, has attracted little attention due to its poor electrical transport properties and high thermal conductivity. Interestingly, BiSbSe3, a product of alloying 50% Sb on Bi sites, shows outstanding electron and phonon...
Investigations on electrical and thermal transport properties of Cu2SnSe3 with unusual coexisting nanophases
The ternary diamond-like compound Cu2SnSe3 is a potential thermoelectric material. Its Cu-Se conducting network leaves Sn as a likely doping site to optimize the carrier concentration without much deterioration to the carrier mobility. Thus, the precise determination on the intricate phase structures of Cu2SnSe3 is...
STEM-in-SEM highly deformed structure investigation with focus on electron-transparent specimen preparation
Many factors affect the outcome and effective spatial resolution of STEM-in-SEM analyses, such as the material density, material atomic number, electron beam voltage, detector type, and specimen preparation (especially specimen thickness and uniformity). The latter of these, specimen preparation, appears to be one...
Synergistic compositional-mechanical-thermal effects leading to a record high zT in n-type V2VI3 alloys through progressive hot defo...
Here a progressive hot deformation procedure that endows the benchmark n-type V2VI3 thermoelectric materials with short range disorder (multiple defects), long range order (crystallinity), and strong texture (nearly orientation order) is reported. Not only it is rare for these structural features to coexist but also...
The structural origin of enhanced piezoelectric performance and stability in lead free ceramics
Lead-based piezoelectric materials are currently facing global restrictions due to their lead toxicity. Thus it is urgent to develop lead-free substitutes with high piezoelectricity and temperature stability, among which, potassium-sodium niobate [(K,Na)NbO3, KNN] has the most potential. It is very difficult to...
