> **NEW START.** $18.1M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $18.1M in FY2027, 64% of project A61 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Will investigate alternative diamond substrate configurations to enable epitaxial overgrowth of diamond and cubic boron nitride thin films to fabricate high-power, small form-factor radio frequency (RF) devices; research topological, two-dimensional, and magnetic materials and heterostructures to devise concepts for electromagnetic (EM) and event-based sensing for electronic support functions of electronic warfare (EW); explore electrochemical stability and rate capabilities of new battery electrolyte compositions at elevated temperatures; conduct experiments on the electrochemical synthesis of ammonia for energy storage and related photocatalytic ammonia decomposition; conduct experiments on nitride heterostructures to explore the relationships between polarization switching kinetics and semiconductor conductivity, aiming to validate power diversion and amplification concepts; research polarization-sensitive detection of EM signals at wavelengths ranging from infrared (IR) to Terahertz; analyze and validate alpha-voltaic power conversion of ultrawide bandgap (UWBG) aluminum gallium nitride (AlGaN) and diamond vertical device designs coupled to Americium-241 (Am-241) radioisotope for persistent stand-in sensing; investigate optical modulator components derived from potassium tantalate niobate materials in an integrated photonic circuit; explore incorporating constraints in machine learning (ML) surrogate models of complex physical systems; conduct research into ML surrogate models of history-dependent physical systems; model the responsivity of quantum materials to polarized electromagnetic signals; examine how Monte Carlo based materials parameters impact performance of UWBG Technology Computer Aided Design (TCAD) device models.

**FY2026 to FY2027 change.** FY 2027 funding increase reflects the consolidation of other ongoing efforts within this project from Beyond Novel Materials, Compact Non-Linear Elements and Non-Linear Arrays, Novel Materials and Architectures for Emerging Bands and Modalities, Physics Research for Army Innovation, Physics-informed Machine Learning for Complex Phenomena, and Semiconductor Modeling for Advanced Electronics to support the creation of Electronic Warfare (EW) Enabling Electronic and Photonic Physical Phenomena (E3P3).

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2027 | Request | 18.1 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
