Positron and Pair Production
The image illustrates particle pair production(γ —> e- +e+) , showing the track of an electron (e-)and a positron (e+). The existence of this antimatter particle was a direct theoretical consequence of P.A.M. Dirac's equation from 1928, commonly expressed as:
The negative energy solutions of this equation led to the prediction of the positron. Carl Anderson experimentally confirmed the positron in cosmic rays in 1932. Dirac shared the 1933 Nobel Prize in Physics for this theoretical work, and Anderson shared the 1936 Nobel Prize for the experimental discovery.
Chinese scientist Zhao Zhongyao discovered the high-energy photon beam of hard γ-rays in 1929, with his findings published in the American journal Physical Review in 1930 under the title "Scattering of Hard γ-Rays." He was the first person to observe the phenomenon of electron-positron pair production and annihilation.
About Us
Xian Electron focuses on innovative materials and semiconductor technologies to solve the core challenges of the AI computing surge and the commercial space era. Our founding team brings over two decades of deep expertise across global frontiers, having led multiple technology benchmarks with worldwide impact—including the world’s first silicon‑based gallium nitride company, Lattice Power (recipient of the 2015 National Technological Invention First Prize), the HJT thin‑film technology company Silevo (later acquired by Elon Musk), Ronbay Technology (the largest cathode material supplier to CATL), and the GaN‑chip company GaN Systems (acquired by Infineon in 2023). Through these pioneering technologies, we are driving transformative changes in the global energy landscape.
Responding to the surging demand for AI compute and the large‑scale deployment of commercial space systems, the company drives innovation with a dual‑engine approach: SST Energy Router × Space‑grade Photovoltaics, continuously expanding our core application scenarios.
In AI data centers, our SST Energy Router reconfigures power distribution with an innovative topology, achieving millisecond‑level load smoothing and dramatic efficiency improvements.
In commercial aerospace, our Tianjin intelligent manufacturing hub focuses on space‑grade power supplies and electronic control systems: we have developed a fully automated production line for Hall‑effect electric propulsion power units (PPCU), delivering high‑precision, high‑reliability satellite power products; we offer a unique “energy harvesting + management” integrated solution for satellite photovoltaic power, precisely aligned with the cost‑reduction needs of large‑scale commercial space missions; and based on low‑cost modular space power products, we provide stable, reliable power supplies and total solutions for aerospace and near‑space vehicles.
Rooted in fundamental materials science, we continuously refine precision manufacturing processes. Backed by three core technology pillars—vapor‑phase epitaxy, space‑grade thermal management, and high‑rate advanced materials—we relentlessly push the boundaries of cost and efficiency in energy systems, contributing to humanity’s vision of sustainable energy.
