Introduction

Inventor Ji Hao, based in Boston, MA, has made significant contributions to the field of ion and radiation detection technologies. With a total of three patents to his name, Ji's work focuses on developing devices that utilize cutting-edge materials for sensitive and reliable detection of ionizing radiation.

Latest Patents

Ji Hao's latest innovations include advanced ion and radiation detection devices that employ carbon nanomaterials and two-dimensional nanomaterials. These devices are characterized by their ultrasensitivity, miniaturization, and cost-effectiveness. The detection apparatus consists of an insulating substrate with metallic contact pads, and a strip of ultrathin two-dimensional material, measuring merely one or a few atomic layers in thickness. When voltage is applied across this two-dimensional sensor, individual ions interacting with the material modify the current flow, enabling precise detection of high-energy ions and ionizing radiation.

Another cutting-edge patent from Ji involves the development of ion-doped two-dimensional nanomaterials. These materials are achieved by inducing electronic carriers—electrons and holes—within a two-dimensional structure using a captured ion layer at the surface. The ion layer is further stabilized via a capping layer, allowing for high carrier density, which supports the creation of a range of novel ion-doped nanomaterials and p-n junction-based nanoelectronic devices.
