According to Nature, characterizing the performance and assessing the technological potential of devices based on emerging semiconductors such as perovskites presents significant challenges. The research community’s focus on alternative materials to overcome physical limits of current semiconductors creates new testing complexities that third-party certification and standardized approaches could help address. This measurement gap represents a critical bottleneck in the commercialization pipeline.

The Semiconductor Evolution Beyond Silicon
While silicon has dominated electronics for decades, researchers have been exploring alternative materials that offer unique advantages. Gallium arsenide provides superior electron mobility for high-frequency applications, while silicon carbide excels in high-temperature and high-power environments. The current wave of emerging materials includes perovskites, which demonstrate remarkable optoelectronic properties for solar cells and light-emitting devices, along with organic semiconductors that enable flexible electronics and 2D materials like graphene that offer atomic-scale thinness. Each material system requires fundamentally different characterization approaches because their performance metrics, degradation mechanisms, and operational limits vary dramatically from traditional silicon-based transistors.
The Standardization Crisis in Emerging Tech
The characterization challenge extends beyond technical difficulty to a fundamental reproducibility crisis. Research groups worldwide use different testing protocols, environmental conditions, and measurement equipment, making direct comparisons between published results nearly impossible. This lack of standardization creates a “wild west” environment where breakthrough claims cannot be independently verified, potentially leading to wasted research funding and misguided commercial investments. The problem is particularly acute for perovskite materials where stability testing protocols vary so widely that lifetime predictions range from months to decades depending on the methodology. Without industry-wide testing standards, investors cannot accurately assess technological readiness levels, creating a valley of death between laboratory demonstrations and commercial deployment.
Market Consequences of Measurement Uncertainty
This characterization gap has tangible market impacts that extend throughout the electronics ecosystem. Venture capital firms are becoming increasingly cautious about funding emerging semiconductor startups due to the difficulty in validating performance claims. Large semiconductor manufacturers face challenges in technology acquisition because they cannot reliably assess whether laboratory results will translate to manufacturable processes. The situation creates a paradox where promising materials may be abandoned not because they lack potential, but because their potential cannot be properly measured and compared against incumbent technologies. This measurement uncertainty particularly disadvantages smaller research institutions and startups that lack the resources to conduct comprehensive characterization studies, potentially causing viable technologies to be overlooked.
Pathways to Reliable Emerging Tech Assessment
The solution requires coordinated action across multiple stakeholders. Research institutions must adopt standardized testing protocols similar to those developed for silicon technology decades ago. Independent certification laboratories need to emerge specifically for emerging semiconductors, providing third-party validation that investors and manufacturers can trust. Professional organizations like IEEE should establish working groups focused on characterization standards for specific material families. The timeline for resolving these challenges is critical – if standardization efforts take too long, promising technologies may lose funding and momentum. However, if the community addresses these measurement issues within the next 2-3 years, we could see accelerated commercialization of multiple emerging semiconductor platforms, potentially enabling entirely new electronics applications that silicon cannot address.
