Title: Marie-Antoinette Poisson: A Pioneer in Semiconductor Technology

Introduction

Marie-Antoinette Poisson is a notable inventor based in Paris, France. She has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. Her innovative work has paved the way for advancements in electronic devices.

Latest Patents

One of her latest patents is a semiconductor device for electron emission in a vacuum. This device comprises a stack of two or more semiconductor layers of N and P type, forming a juxtaposition of two head-to-tail NP junctions. The materials used belong to the III-N family, with adjacent layers forming an interface. The semiconductor materials close to the vacuum allow electrons to reach high energy levels, with a band gap greater than half the electron affinity of the semiconductor material. The P-type semiconductor layer is obtained through doping impurities or by the piezoelectric effect, exhibiting a negative fixed charge at the interface. A positive bias potential applied to the stack provides the necessary energy for electron emission in the vacuum.

Another significant patent is a bipolar transistor with an optimized structure. In this design, the emitter features a double 'mesa' structure to minimize electron/hole recombinations that negatively impact current gain. The double mesa emitter can be constructed from alternating materials with different etching behaviors, such as GaInP and GaAs.
