Title: Innovations of Randy G Simmons

Introduction

Randy G Simmons is a notable inventor based in San Jose, California. He has made significant contributions to the field of spin-orbit torque (SOT) devices, holding a total of five patents. His work focuses on enhancing the performance and efficiency of these advanced technologies.

Latest Patents

One of his latest patents is titled "SOT reader with recessed SOT topological insulator material." This invention relates to SOT devices that incorporate a bismuth antimony (BiSb) layer. The design includes a first shield, a BiSb layer positioned over the first shield, a free layer (FL) above the BiSb layer, and a second shield over the FL. The BiSb layer is recessed from the media facing surface (MFS) by a distance ranging from 5 nm to 20 nm. The configuration allows current to flow vertically through the SOT to the FL and horizontally from the FL to the BiSb layer.

Another significant patent is "Highly textured 001 BiSb and materials for making same." This patent describes an SOT device featuring a first BiSb layer with a (001) orientation and a second BiSb layer with a (012) orientation. The first BiSb layer is created by depositing an amorphous material on a substrate, which is then exposed to form an amorphous oxide surface. This innovative approach optimizes the signal through the SOT device, balancing performance across both BiSb layers.
