About the role

  • You will translate device physics into manufacturable, high-yield emitters that meet aggressive targets for efficiency, speed, and array uniformity, working across the full stack from epitaxy and process integration to on-wafer test.

Responsibilities

  • Device design & modeling: Develop and optimize GaN-based microLED device structures, including epitaxial layer stacks, active regions, and contact schemes, using TCAD and analytical models to hit efficiency, bandwidth, current-density and reliability targets.
  • Fabrication & integration: Define and refine process flows in collaboration with process integration and foundry partners; own device-level design-of-experiments from wafer to characterization.
  • Electro-optical characterization: Design and execute L-I-V, spectral, modulation-bandwidth, and reliability-relevant measurements on single devices and large arrays; correlate results to design and process parameters.
  • Performance improvement: Diagnose loss mechanisms (non-radiative recombination, sidewall effects, current crowding) and drive design/process changes to improve wall-plug efficiency and high-speed performance.
  • Cross-functional collaboration: Partner with epitaxy, process, packaging, test, and systems teams to align device performance with link-level and product requirements.
  • Documentation: Establish device specifications, test plans, and technical reports; contribute to IP generation and internal design reviews.
  • Define and refine process flows in collaboration with process integration and foundry partners; own device-level design-of-experiments from wafer to characterization.
  • Design and execute L-I-V, spectral, modulation-bandwidth, and reliability-relevant measurements on single devices and large arrays; correlate results to design and process parameters.
  • Diagnose loss mechanisms (non-radiative recombination, sidewall effects, current crowding) and drive design/process changes to improve wall-plug efficiency and high-speed performance.
  • Partner with epitaxy, process, packaging, test, and systems teams to align device performance with link-level and product requirements.

Requirements

  • Characterization: Proven expertise in electro-optical device characterization and data analysis (L-I-V, spectral, high-speed/modulation measurements).
  • Process fluency: Working knowledge of semiconductor fabrication processes (lithography, etch, deposition, metallization) and their impact on device performance.
  • Tools: Proficiency with data analysis and scripting tools (e.g., Python, MATLAB) and TCAD or equivalent device simulation.
  • Working knowledge of semiconductor fabrication processes (lithography, etch, deposition, metallization) and their impact on device performance.

Nice to have

  • GaN microLEDs: Prior hands-on experience with GaN-based microLED devices is strongly preferred but not required.
  • High-speed / high-bandwidth LED or VCSEL device experience for optical interconnect or display applications.
  • Experience with large-area or high-density emitter arrays and array-level uniformity/yield.
  • Track record of patents or peer-reviewed publications in optoelectronic devices.
  • Avicena is an Equal Opportunity Employer.
  • Applicants must be authorized to work in the United States.

Skills

  • Proficiency with data analysis and scripting tools (e.g., Python, MATLAB) and TCAD or equivalent device simulation.
