Claim:
1. A method for low emission charge neutralization, comprising: generating an alternating current (AC) and a high voltage; transmitting the high voltage to at least one point type silicon based non-metallic ion emitter configured with a tip, a taper, a shaft, and a tail; wherein the taper is between the tip and the shaft; wherein the shaft is between the taper and the tail; wherein the high voltage and alternating current is in a high frequency range of 1 kilohertz to 100 kilohertz; wherein the at least one point type silicon based non-metallic ion emitter comprises more than 72.00% silicon by weight and less than 99.99% silicon by weight; wherein the at least one point type silicon based non-metallic ion emitter comprises at least a portion of treated surface of the shaft or/and tail with an increased surface conductivity or a lower electrical resistance; and generating ions from the tip of the emitter in response to a contact of the treated surface of the shaft or/and tail of the emitter to the high voltage and the alternating current in the high frequency range.
