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.

An MR/FIR light detector is disclosed herein that has extraordinarily high degree of sensitivity and a high speed of response. The detector includes an MR/FIR light introducing section (1) for guiding an incident MR/FIR light (2), a semiconductor substrate (14) formed with a single-electron transistor (14) for controlling electric current passing through a semiconductor quantum dot (12) formed therein, and a BOTAI antenna (6, 6a, 6b, 6c) for concentrating the MW/FIR light (2) into a small special zone of sub-micron size occupied by the semiconductor quantum dot (12) in the single-electron transistor (14). The quantum dot (12) forming a two-dimensional electron system absorbs the electromagnetic wave concentrated efficiently, and retains an excitation state created therein for 10 nanoseconds or more, thus permitting electrons of as many as one millions in number or more to be transferred with respect to a single photon absorbed. zing a sample of molecules comprising the steps of: (a) using a tailored waveform having at least two gaps in frequency space for an accumulation time to segregate a subset of ionized molecules from a plurality of ionized molecules; (b) reacting the subset of ionized molecules with a quencher for a charge reduction period to reduce the charge state of ionized molecules in the subset of ionized molecules; (c) determining a mass signal for the ionized molecules having the highest mass to charge ratio resulting from step (b); and (d) repeating steps (a)-(c) for at least another accumulation time. 11. The method of claim 10 further comprising the step of repeating at least steps (a)-(c) for at least another tailored waveform having a different at least two gaps in frequency space to define a mass spectrum. 12. The method of claim 10 wherein step (d) is repeated so the subset of ionized molecules attains at least a minimum abundance. 13. The method of claim 10 further comprising the step of normalizing the mass signal resulting in step (c) based on the accumulation time. 14. The method of claim 10 wherein step (a) comprises selecting at least two gaps in frequency space such that the subset of ionized molecules comprises ionized molecules within mass to charge ratio ranges with median values which are substantially the mass-to-charge ratios of the integer charge states of a select ion mass. 15.
