Title: Haifeng He: Innovator in Electron Diffraction Tomography

Introduction

Haifeng He is a notable inventor based in Rockville, MD (US). He has made significant contributions to the field of electron diffraction tomography, particularly through his innovative methods that enhance the capabilities of Transmission Electron Microscopes (TEM).

Latest Patents

Haifeng He holds a patent for a "Method of Electron Diffraction Tomography." This invention relates to a method for electron diffraction tomography in a Transmission Electron Microscope. Traditional methods typically involve using a Scanning Transmission Electron Microscope (STEM) and utilize a scanned beam for STEM diffraction. However, He’s invention proposes to form the diffraction patterns using a stationary beam with a diameter slightly larger than the crystal. This allows for the use of a TEM without a STEM unit. The crystal is located in TEM mode, which offers several advantages. Notably, a TEM without a scanning unit can be employed, and the diffraction volume is independent of the crystal's orientation, as the entire crystal is illuminated while obtaining the diffraction pattern. He has 1 patent to his name.
