Thermal Management
Diamond Thermal Boundary Resistance: Why Conductivity Is Not Enough
A diamond heat spreader can have outstanding bulk conductivity and still be limited by its bonds. Compare material-layer and interface resistance on the same area basis.
Materials Evaluation
How to Evaluate a Diamond Wafer Beyond Its Diameter
A wafer's quoted diameter is not its application-ready area. Compare growth routes, defect maps, stress, thickness variation, and the maturity of supplier claims.
Process Fundamentals
How to Read MPCVD Process Parameters
Published single-crystal and polycrystalline diamond experiments put MPCVD pressure, temperature, power, and gas ratios in context without turning them into a portable recipe.
Process Fundamentals
Single-Crystal vs Polycrystalline CVD Diamond
CVD and HPHT describe how diamond is made; single-crystal and polycrystalline describe its structure. Compare practical size, grain boundaries, and thermal behavior.
Thermal Management
Heat Spreader vs. Heat Sink: Spreading Heat Is Not the Same as Removing It
A heat spreader reduces local heat flux by distributing a hotspot; a heat sink transfers heat to air or liquid. Effective packages normally need both, plus well-controlled interfaces.
Process Fundamentals
How Synthetic Diamond Is Made: HPHT, CVD, MPCVD, and HFCVD
A practical comparison of HPHT, CVD, MPCVD, HFCVD, and detonation routes—and how each process maps to different diamond products and applications.
Thermal Management
Diamond Heat Spreaders and Diamond Substrates Are Not the Same Product
Diamond heat spreaders and diamond substrates may look similar, but they solve different engineering problems and must be evaluated against different specifications.
Process Fundamentals
MPCVD Explained: How Microwave Plasma Grows CVD Diamond
A practical introduction to MPCVD, covering plasma-assisted diamond growth, reactor architecture, material classes, engineering challenges, and the difference between making a sample and running a repeatable process.
Thermal Management
Why CVD Diamond Is Considered for Advanced Thermal Management
CVD diamond combines exceptional heat spreading with electrical insulation, but useful products still depend on interfaces, metallization, bonding, geometry, reliability, and cost.
Quantum Applications
Why NV-Center Applications Need Controlled, High-Purity Diamond
NV centers are useful defects, but quantum performance depends on controlling unwanted impurities, lattice damage, isotopes, surfaces, concentration, and defect location.
