The story
Cyclopentadienyl magnesium compounds are among the most effective precursors for magnesium-containing thin film deposition. They are highly volatile, thermally stable, and strongly reactive toward co-reagents — making them the preferred choice for MOCVD and ALD of magnesium oxides, magnesium fluorides, magnesium nitrides, and magnesium-doped semiconductors.
They are also pyrophoric. They ignite spontaneously on contact with air.
Ereztech has built its magnesium precursor practice around that reality. We have purpose-built pyrophoric handling laboratories, purpose-trained staff, and purpose-designed processes for manufacturing, packaging, and shipping these materials safely at scale. Pyrophoric chemistry is not a side capability here — it is a core competency.
And for customers who need the performance of magnesium cyclopentadienyl chemistry without the pyrophoric handling burden, we developed something nobody else offers: a family of non-pyrophoric amine adduct variants, available commercially today.
The Pyrophoric Precursor Family
MgCp₂
The most widely used p-dopant for GaN-based semiconductors including GaAs, AlGaAs, and InP. Also applied for MgO buffer layers and magnesium metal film deposition. White crystalline solid, 99% purity.
Mg(MeCp)₂
Used for Mg incorporation in MOVPE GaN and growth of ZnSe, ZnSSe, and ZnMgSSe thin films. White crystalline solid, 99% purity.
Mg(EtCp)₂
Colorless to yellow liquid. Versatile reagent for advanced materials synthesis and magnesium-centered organometallic chemistry. 99% purity.
All three are manufactured under full pyrophoric safety protocols and are available in any packaging format, including custom vessel configurations for your deposition system.
The Ereztech-Developed Non-Pyrophoric Alternative
For researchers and process engineers who require the performance characteristics of magnesium cyclopentadienyl chemistry but operate without specialized pyrophoric handling infrastructure, Ereztech has developed a family of amine adduct complexes that eliminates spontaneous ignition while preserving the precursor properties that matter.
These Ereztech-developed compounds pair Mg(MeCp)₂ and Mg(EtCp)₂ with a range of diamine ligands — TMEDA, TEEDA, TMPDA, and TMBDA — yielding six distinct complexes with tunable thermal and volatility profiles. All six show clean evaporation with less than 0.5% residue above 200°C and no spontaneous ignition on air exposure. ¹H NMR, ¹³C NMR, and X-ray crystallography have verified purity and structure.
All six variants are commercially available. No other supplier offers this class of compounds.
Applications
Magnesium cyclopentadienyl precursors – pyrophoric and non-pyrophoric – are used across a growing range of thin film applications:
Semiconductor doping – p-type doping of GaN, GaAs, AlGaAs, InP, and related III-V materials for LEDs, power electronics, and RF devices
Optical coatings – magnesium fluoride thin films for anti-reflection and UV optical coatings
Electrical insulation – magnesium oxide films for dielectric and passivation layers
Energy storage – magnesium-containing films for next-generation battery and capacitor applications
Superconductor buffering – MgO as a passivating buffer layer for YBCO and REBCO deposition on semiconductor substrates
