Abstract
A nano/micro-sized diode and a method of preparing the same, the diode including: a first electrode; a second electrode; and a diode layer that is disposed between the first electrode and the second electrode. The diode layer includes a first layer and a second layer. The first layer is disposed on the first electrode and has a first surface that is electrically connected to the first electrode, and an opposing second surface that has a protrusion. The second layer is disposed between the first layer and the second electrode and has a first surface having a recess that corresponds to the protrusion, and an opposing second surface that is electrically connected to the second electrode.
Claims18
A nano/micro-sized diode comprising:
- a first electrode;
- a second electrode;
- and
- a diode layer disposed between the first electrode and the second electrode, the diode layer comprising,
- a first layer disposed on the first electrode, having a first surface that is electrically connected to the first electrode, and an opposing second surface having a protrusion, and
- a second layer disposed between the first layer and the second electrode, having a first surface having a recess corresponding to the protrusion, and an opposing second surface that is electrically connected to the second electrode.
A method of preparing a nano/micro-sized diode, comprising:
- forming first electrodes in holes of a porous template;
- applying material layers onto the first electrodes;
- heat treating the material layers, to form first layers that each has a first surface that is electrically connected to the first electrode, and an opposing second surface that has a protrusion;
- forming second layers on the first layers, the second layers each having a first surface having a recess that corresponds to a respective one of the protrusions;
- forming second electrodes on the second layers;
- and
- removing the porous template, to obtain nano/micro-sized diodes.
