I. Breakthrough Research on Materials and Performance Limits
1.The deepening of the concept of “phonon glass – electronic crystal”: •
Latest achievement: Researchers have accelerated the screening process for potential materials with extremely low lattice thermal conductivity and high Seebeck coefficient through high-throughput computing and machine learning. For instance, they discovered Zintl phase compounds (such as YbCd2Sb2) with complex crystal structures and cage-shaped compounds, whose ZT values exceed those of traditional Bi2Te3 within specific temperature ranges. •
“Entropy engineering” strategy: Introducing compositional disorder in high-entropy alloys or multi-component solid solutions, which strongly scatters phonons to significantly reduce thermal conductivity without seriously compromising electrical properties, has become an effective new approach for enhancing the thermoelectric figure of merit.

The latest research focuses on integrating micro TEC，micro thermoelectric module， (thermoelectric cooling module), peltier elements, and silicon-based chips monolithically (in a single chip). Using MEMS (Micro-Electro-Mechanical Systems) technology, micro-scale thermoelectric column arrays are directly fabricated on the backside of the chip to provide “point-to-point” real-time active cooling for local hotspots of CPUs/GPUs, which is expected to break through the thermal bottleneck under the Von Neumann architecture. This is considered one of the ultimate solutions to the “heat wall” problem of future computing power chips.
2. Self-powered thermal management for wearable and flexible electronics:
Combining the dual functions of thermoelectric power generation and cooling. The latest achievements include the development of stretchable and high-strength flexible thermoelectric fibers. These can not only generate electricity for wearable devices by utilizing temperature differences， but also achieve local cooling (such as cooling special work uniforms) through reverse current， achieving integrated energy and thermal management.

In cutting-edge fields such as quantum bits and high-sensitivity sensors, ultra-precise temperature control at the mK (millikelvin) level is essential. The latest research focuses on multi-stage TEC, multi- stage peltier module (thermoelectric cooling module) systems with extremely high precision (±0.001°C) and explores the use of TEC module ,peltier device, peltier cooler, for active noise cancellation, aiming to create an ultra-stable thermal environment for quantum computing platforms and single-molecule detection devices.
