Materials Chemist specializing in 2D Materials

About Albert García

In 2019, Albert García led the team that first demonstrated scalable electrochemical exfoliation of boron nitride nanosheets directly onto flexible PET substrates, enabling wafer-scale integration without transfer steps, a bottleneck plaguing graphene electronics. Based at the Institute of Materials Science of Barcelona (ICMAB-CSIC), he bridges synthetic precision and device pragmatism: his lab’s custom-built ambient-pressure CVD reactor allows real-time Raman monitoring during MoS₂ growth, revealing how sulfur partial pressure governs defect density at sub-500°C. Fluent in Catalan, Spanish, and English, he co-developed the open-source '2DMatSim' toolkit for predicting stacking-dependent band alignments in van der Waals heterostructures, used by over 37 academic labs across Europe. His notebooks, digitized and annotated on Zenodo, show iterative failures with lithium-intercalated TaS₂ before achieving room-temperature superconductivity signatures in twisted bilayers, a result later validated by ETH Zurich’s low-T transport group.

  • “How did your 2019 BN exfoliation method bypass the graphene transfer problem?”
  • “What sulfur pressure range gives optimal MoS₂ mobility in your CVD setup?”
  • “Why does '2DMatSim' use Wannier interpolation instead of DFT for band alignment?”
  • “Can twisted TaS₂ retain superconductivity above 10K in air-stable encapsulation?”

Frequently Asked Questions

Did Albert García contribute to the EU Graphene Flagship Phase 2 materials work package?
Yes—he co-led Work Package 4 (‘2D Material Synthesis & Integration’) from 2021–2023, focusing on reproducible wafer-scale synthesis of h-BN dielectrics. His team delivered three standardized protocols adopted by six Flagship partners, including a solvent-free dry-transfer technique for large-area h-BN/graphene stacks.
What is Albert García’s stance on the commercial viability of 2D-material-based flexible sensors?
He argues viability hinges not on sensitivity alone but on environmental stability under cyclic strain. His 2022 ACS Nano paper showed that edge-passivated phosphorene transistors retained >92% responsivity after 10⁴ bending cycles at 5mm radius—outperforming graphene analogues due to suppressed oxygen adsorption at reconstructed edges.
Has García published on toxicity or environmental impact of 2D material synthesis?
Yes—in 2023, his group published life-cycle assessment data comparing electrochemical vs. liquid-phase exfoliation of MXenes. They found that using recycled graphite anodes and pulsed current reduced energy demand by 68% and eliminated HF waste, a finding now cited in EU REACH guidance drafts.
Does García collaborate with semiconductor foundries on 2D integration?
Since 2020, he’s partnered with STMicroelectronics’ Agrate facility on integrating WS₂ channel layers into 28nm-node test chips. Their joint process flow achieved sub-100nm channel lengths with gate leakage <10⁻¹² A/μm—published in IEEE TED—and is under evaluation for IR photodetector pilot lines.
