연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Methods, systems, and devices are disclosed for precision fabrication of nanoscale materials and devices. In one aspect, a method to manufacture a nanoscale structure include a process to dissociate a feedstock substance including a gas or a vapor into constituents, in which the constituents include individual atoms and/or molecules. The method includes a process to deposit the constituents on a surface at a particular location. The method includes a process to grow layers layer by layer using two or more particle and/or energy beams to form a material s...

1. A method to manufacture an engineered material, the method comprising: directing two or more beams to a particular location in a three dimensional space to dissociate a feedstock substance including a gas or a vapor into constituents, the constituents including individual atoms or molecules, wherein the directing the two or more beams causes at least one of the constituents of the dissociated feedstock substance to deposit at a deposition site proximate the particular location; andforming layers of deposited constituents layer by layer in one or more dimensions to produce a material structure, wherein the forming the layers includes dissociating an additional feedstock substance into additional constituents by directing the two or more beams to a location proximate a previously deposited constituent to cause at least one of the additional constituents of the dissociated additional feedstock substance to deposit on a constituent deposition site of the previously deposited constituent,wherein—the two or more beams include at least one of a laser beam or an atomic particle beam, andthe feedstock substance includes dichloroethane including a vinylhalide. 2. The method of claim 1, wherein the feedstock substance includes at least one of methane, ethane, propane, butane, or other paraffin. 3. The method of claim 2, wherein the produced material structure includes a carbon product, wherein dissociation of the feedstock substance produces excess hydrogen gas formed as a by-product. 4. The method of claim 3, further comprising: collecting the hydrogen gas in a collection chamber. 5. The method of claim 1, wherein the feedstock substance includes one or more of nitrogenous molecules, hydrocarbon molecules, metal organic feedstocks including Fe, Ni, Cu, or Co carbonyls or functional groups, or halogenated compounds. 6. The method of claim 1, wherein the produced material structure includes coaxial tubes of cylindrical or conical geometries, wherein the forming the layers includes producing HCI formed as a by-product. 7. The method of claim 1, further comprising: preheating the feedstock substance prior to the directing the two or more beams to dissociate the feedstock substance,wherein the preheating minimizes required energy to dissociate the feedstock substance into the constituents. 8. The method of claim 1, wherein the deposition site proximate the particular location is located on a substrate surface. 9. The method of claim 8, wherein the dissociating the feedstock substance further includes applying heat to the substrate surface to form at least an initial layer. 10. The method of claim 8, further comprising: moving the substrate surface in one or more directions to control deposition of the constituents. 11. The method of claim 8, further comprising: cleaving the material structure from the substrate surface. 12. The method of claim 1, wherein the method is implemented in a sealed chamber. 13. The method of claim 1, wherein the deposition site proximate the particular location includes a portion of a constituent material previously dissociated from a gas or vapor feedstock substance. 14. The method of claim 1, wherein the atomic particle beam is configured to produce a polarity at the particular location of the deposition site. 15. The method of claim 1, wherein the directing the two or more beams causes molecular bonds of the feedstock substance to break. 16. The method of claim 1, wherein the two or more beams include laser beams including a columnated- or laser-generated ultraviolet (UV), optical or infrared (IR) frequencies. 17. The method of claim 1, wherein the two or more beams include a first laser beam set at a first frequency to dissociate the feedstock substance and a second laser beam set at a second frequency to form the deposit of the dissociated constituent at a deposition site. 18. The method of claim 17, wherein the first and the second laser beams are joined to produce a combination beam. 19. The method of claim 18, wherein the first and the second laser beams are joined by one or more mirrors, fibers, or tubes. 20. The method of claim 1, wherein the two or more beams are cyclically provided in simultaneous or sequential events. 21. A method to fabricate an engineered material, the method comprising: providing a first energy of association to a first gas or vapor feedstock substance by directing one or more beams to a first location in three dimensional space, the providing the first energy including dissociating the first gas or vapor feedstock substance into a first group of constituents including individual atoms or molecules;providing a second energy of association to a second gas or vapor feedstock substance by directing the one or more beams to a second location proximate the first location, the providing the second energy including (i) dissociating the second gas or vapor feedstock substance into a second group of constituents and (ii) forming a bond between at least one of the dissociated constituents of the second group and at least one of the dissociated constituents of the first group to produce a material deposit; andcreating a material structure deposit by sequentially bonding deposits of dissociated constituents to the material deposit by directing the one or more beams to further dissociate additional gas or vapor feedstock substances and form bonds between their constituents and the material deposit,wherein—the directed one or more beams include one or both of a laser beam and an atomic particle beam,the feedstock substance includes dichloroethane including a vinylhalide, andthe feedstock includes at least one of methane, ethane, propane, butane, or other paraffin. 22.
