Patents by Inventor Bert de Boer

Bert de Boer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9559320
    Abstract: Described is a modulatable injection barrier and a semiconductor element comprising same. More particularly, the invention relates to a two-terminal, non-volatile programmable resistor. Such a resistor can be applied in non-volatile memory devices, and as an active switch e.g. in displays. The device comprises, in between electrode layers, a storage layer comprising a blend of a ferro-electric material and a semiconductor material. Preferably both materials in the blend are polymers.
    Type: Grant
    Filed: September 14, 2011
    Date of Patent: January 31, 2017

  • Patent number: 9246117
    Abstract: Described is an (organic) light-emitting diode ((O)LED) wherein the light-emitting layer comprises a blend of an electroluminescent semiconducting material with a ferro-electric material. Either of the electrodes forms a modulatable injection barrier with the ferro-electric material, the modulation requiring a voltage Vm serving to polarize or repolarize the ferro-electric material. With Vm being larger than the voltage Ve required for light emission, the (O)LED can be turned “on” or “off” by applying a pulse voltage to (re)polarize the ferro-electric material.

  • Patent number: 6271308
    Abstract: The present invention relates to a stable polymer composition comprising a first polymer and a second polymer, which second polymer is not compatible with the first polymer, and an amount of a copolymer comprising at least one block of a polyalkadiene and at least one block of random poly(aromatic vinyl-acrylonitrile), and in which the ratio of the block copolymer to the total polymer composition is between 1:500 and 1:50. Besides, the invention relates to the use of the above block copolymer as compatibilizer and/or as modifier for the mechanical properties of polymer compositions.
