Abstract

Abstract An electron emission device has a first metal layer (4), an insulation layer (6) formed on the first metal layer, a second metal layer (8) formed on the insulation layer, and means for applying a voltage across the first and second metal layers to cause the second metal layer to emit electrons. The insulation layer includes an organic insulation layer.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 60 words
An electron emission device having a first metal layer, an insulation layer formed on the first metal layer, a second metal layer formed on the insulation layer and means for applying a voltage across said first and second metal layers to cause said second metal layer to emit electrons, characterized in that said insulation layer includes an organic insulation layer.
Claim 2
Dependent Claim 60 words
An electron emission device having a first metal layer, an insulation layer formed on the first metal layer, a second metal layer formed on the insulation layer and means for applying a voltage across said first and second metal layers to cause said second metal layer to emit electrons, characterized in that said insulation layer includes an organic insulation layer.
Claim 3
Dependent Claim 40 words
An electron emission device according to Claim 1, wherein said organic insulation layer is made of fatty acid including stearic acid, arachidic acid, palmitic acid, azulene squarilium dye and derivative of diacetylene, and formed by a single molecule accumulation method.
Claim 4
Dependent Claim 28 words
An electron emission device according to Claim 1, wherein said organic insulation layer is made of n-paraffin, hexatriacontan or stearic acid, and formed by a vapor deposition method.
