Abstract
The present invention is a method and apparatus for the synthesis of multi-component substances, comprising entities of at least two elements, molecules, grains, crystals, structural units, or phases of matter, in which the scale of the distribution of the elements, molecules, or phases of matter may range from on the order of nanometers or less, to about one millimeter, depending upon the specific materials and process conditions that are chosen. The method and apparatus of the present invention further provides processes for preparing these compositions of matter as thin films or particles.
Claims49
A method for harvesting a multi-component substance with a harvesting device, comprising the steps of:
- (a) applying energy from an energy source to a first target assembly wherein said first target assembly is comprised of a first material and a second material;
- (b) ablating said first material from said first target assembly and generating a first plasma having a temperature of at least 2000 degrees Centigrade;
- (c) ablating said second material from said first target assembly and generating a second plasma having a temperature of at least 2000 degrees Centigrade;
- (d) discharging a flow of reagent gas from a gas supply toward said first plasma;
- (e) discharging a flow of reagent gas from a gas supply toward said second plasma;
- (f) reacting said first plasma and said second plasma to produce a multi-component substance;
- (g) discharging a flow of reagent gas from a gas supply toward said harvesting device;
- and
- (h) harvesting said multi-component substance with said harvesting device.
A method for harvesting a multi-component substance with a harvesting device, comprising the steps of:
- a) applying energy from an energy source comprising a direct current power supply of at least 100 volts potential to a first target assembly comprised of a first electrode and a second electrode;
- b) ablating material from said first target assembly and generating a plasma having a temperature of at least 2000 degrees Centigrade by causing an arcing electrical discharge between said first electrode and said second electrode;
- c) discharging a flow of reagent gas from a gas supply toward said plasma
- d) reacting said plasma and said reagent gas to produce a multi-component substance;
- e) discharging a flow of reagent gas from a gas supply toward said harvesting device;
- f) harvesting said multi-component substance with said harvesting device.
A method for harvesting a multi-component substance with a harvesting device, comprising the steps of:
- a) applying energy from a laser to a first laser target assembly comprised of a first material;
- b) applying a voltage from a direct current power supply with at least 100 volts to a first target electrode and a second target electrode;
- c) ablating said first material from said laser target assembly and generating a first plasma having a temperature of at least 2000 degrees Centigrade;
- d) ablating said first and second electrodes and generating a second plasma having a temperature of at least 2000 degrees Centigrade;
- e) discharging a flow of reagent gas from a gas supply toward said first plasma;
- f) discharging a flow of reagent gas from a gas supply toward said second plasma;
- g) reacting said first plasma and said second plasma to produce a multi-component substance;
- h) discharging a flow of reagent gas from a gas supply toward said harvesting device;
- and
- i) harvesting a multi-component substance with said harvesting device.
