Types of Our Services

Customized Epitaxial Growth and Thin Film Synthesis Services

This service line focuses on the precise deposition of high-quality semiconductor thin films using state-of-the-art epitaxial growth techniques, tailored to the specific composition and structural requirements of research projects. Offerings include molecular beam epitaxy (MBE) for ultra-pure, low-defect films (ideal for UWBG materials like Ga₂O₃ and AlN), metal-organic chemical vapor deposition (MOCVD) for scalable growth of compound semiconductors (e.g., GaN, SiC), and pulsed laser deposition (PLD) for complex oxide semiconductors. A specialized subset of this service is the growth of alloyed semiconductor films, such as Al_xGa_1-xO₃ and (Al_xGa_1-x-γIn_γ)₂O₃, with precise control over alloy composition to tune bandgap and electrical properties. For example, we support the growth of Al-substituted Ga₂O₃ films with aluminum content ranging from 0–25%, enabling researchers to study the correlation between alloy composition and breakdown voltage.

High-Precision Material Characterization and Metrology Services

Our characterization services provide comprehensive structural, electrical, and optical analysis of advanced semiconductor materials, delivering quantitative data to validate material quality and performance. Structural characterization techniques include transmission electron microscopy (TEM) for atomic-scale imaging of crystal lattices and defect distributions, X-ray diffraction (XRD) for phase identification and lattice parameter measurement, and Raman spectroscopy for strain and crystallinity assessment. Electrical characterization encompasses Hall effect measurements to determine carrier mobility and concentration, current-voltage (IV) curve analysis for breakdown voltage and leakage current evaluation, and low/high-temperature testing to study thermal stability. Optical characterization tools, such as photoluminescence (PL) spectroscopy, are used to map bandgap energy and identify defect-related emission peaks. These services are designed to integrate seamlessly with research workflows, providing actionable data to refine synthesis parameters and material design.

Computational Material Design and High-Throughput Screening Services

Leveraging advanced computational tools, this service line accelerates material discovery by predicting the properties of novel semiconductor materials and prioritizing candidates for experimental validation. Core capabilities include density functional theory (DFT) simulations to calculate band structures, thermodynamic stability, and defect formation energies, as well as machine learning-driven high-throughput screening of potential material compositions. For example, our computational workflows can generate and screen over 30,000 hypothetical semiconductor compositions using trained ionic translation models, filtering candidates based on redox stability, bandgap energy, and earth-abundance to identify promising materials for specific research applications. This approach reduces the time and resource investment required for experimental exploration, enabling researchers to focus on the most scientifically viable material systems.

Precision Synthesis Technologies

• Molecular Beam Epitaxy (MBE)
  Operated under ultra-high vacuum conditions, MBE enables the deposition of semiconductor thin films with atomic-layer precision by thermally evaporating elemental sources onto heated substrates. CD BioSustainable's MBE systems are specialized for the growth of WBG/UWBG materials (GaN, AlN, Ga₂O₃) and 2D materials (MoS₂, graphene), with dedicated chambers for nitride and oxide materials to prevent cross-contamination. The technique's low deposition rate (0.1–1 monolayer per second) and in-situ monitoring capabilities (reflection high-energy electron diffraction, RHEED) ensure precise control over film thickness and interface quality, critical for heterostructure research such as AlGaN/GaN high-electron-mobility transistor (HEMT) structures.
• Atomic Layer Deposition (ALD)
  ALD enables the growth of ultra-thin, conformal films with sub-nanometer thickness control by alternating exposure of the substrate to gaseous precursors. This technique is ideal for depositing high-quality oxide and nitride thin films (e.g., SiO₂, Al₂O₃) for gate dielectrics and passivation layers in advanced semiconductor research. The self-limiting nature of ALD ensures uniform film growth across large-area substrates and complex geometries, making it suitable for 3D semiconductor structures and 2D material encapsulation.
• Chemical Vapor Deposition (CVD)
  CVD techniques, including plasma-enhanced CVD (PECVD) and metal-organic CVD (MOCVD), are used for scalable growth of semiconductor films and 2D materials. MOCVD is particularly effective for the growth of compound semiconductors (GaN, SiC) using metal-organic precursors (e.g., trimethylgallium, ammonia), enabling high-volume production of epitaxial wafers for research-scale device fabrication. PECVD, which uses plasma to activate precursor gases, is utilized for depositing dielectric films (SiO₂, Si₃N₄) at lower temperatures, preserving the integrity of temperature-sensitive substrates such as 2D materials and organic semiconductors.

Advanced Characterization and Analysis Technologies

Computational and Data-Driven Technologies

• Density Functional Theory (DFT) and Machine Learning (ML)
  DFT simulations are used to predict the electronic and structural properties of semiconductor materials, including bandgap energy, carrier mobility, and defect formation energies, without the need for experimental synthesis. ML algorithms, trained on large databases of existing material properties, enable high-throughput screening of novel compositions to identify candidates with target properties (e.g., optimal bandgap for photoelectrochemical applications). These computational tools accelerate the material discovery process, reducing the time from theoretical concept to experimental validation.
