An ergonomic pointing device is disclosed. The ergonomic pointing device includes a holder mounted to a finger on a users hand and a pointing implement mounted to the holder. The user manipulates the ergonomic pointing device to bring the pointing implement into contact with a device to initiate an action in the device. Optionally, a holster can be connected with the holder to mount the pointing implement on the holder. The pointing implement can be movable in the holder and/or the holster. The holster can be removably connected with the holder. The ergonomic pointing device allows a user to interface with a device without having to use the hand to hold a stylus or the like. The holder can be mounted on the finger using an adhesive and portions of the ergonomic pointing device can be disposable while other portions can be recyclable.

A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

In an electron emitter based on Metal-Insulator-Semiconductor or Metal-Insulator-Metal emitters, field emission structures are enclosed within the emitter structure. The electron emitter may include a conductive substrate and an electron supply layer formed on the conductive substrate. The electron supply layer, for example undoped polysilicon, has protrusions formed on its surface. The sharpness and density of protrusions may be controlled. Above the electron supply layer and the protrusions, an insulator may be formed thereby enclosing the protrusions. A top conductive layer may be formed above the insulator. The enclosed protrusions are relatively insensitive to vacuum contamination. The thinness of the insulator allows high intensity electric fields at the protrusions to be generated with low applied voltage. Field-enhanced injection of electrons into the insulator and thence through the top conductive layer results. Furthermore, electron beam dispersion and divergence are minimized.
