Abstract
One example discloses a heat transfer device that can comprise a semiconductor material having a first region and a second region. The first region and the second region are doped to propel a charged carrier from the first region to the second region. The heat transfer device can also comprise an array of pointed tips thermoelectrically communicating with the second region. A heat sink faces the array, and a vacuum tunneling region is formed between the pointed tips and the heat sink. The heat transfer device further can further comprise a power source for biasing the heat sink with respect to the first region. The first region defines an N-type semiconductor material and the second region defines a P-type semiconductor material.
