Divais SET dapat digunakan untuk banyak aplikasi seperti single electron switching, single photon detector, single electron detector, quantum bit memory, dll. Untuk aplikasi seperti quantum bit memory, diperlukan dua buah quantum dot (QD) yang disusun secara paralel. Pada thesis ini, dua buah SET yang disusun secara paralel disimulasikan dengan software SIMON 2.0 untuk mendapatkan parameter-parameter yang diperlukan guna mengontrol perpindahan elektron antar QD. Dari hasil simulasi, didapatkan bahwa dua buah SET yang disusun secara paralel bertindak sebagai dua buah SET yang independen pada saat junction capacitance antar QD bernilai di atas 5×10–18 F. Perpindahan elektron antar QD terjadi apabila terdapat perbedaan potensial pada dua QD yang melebihi suatu nilai minimum. Nilai minimum tersebut dipengaruhi oleh resistansi dan kapasitansi junction capacitance. Semakin besar resistansi, nilai minimum perbedaan potensial yang diperlukan akan semakin membesar sedangkan apabila kapasitansi semakin besar, nilai minimum perbedaan potensial yang diperlukan akan semakin mengecil. ......SET devices can be used in many applications, such as single electron switching, single photon detector, single electron detector, quantum bit memory, etc. For applications such as quantum bit memory, two quantum dots (QDs) in parallel position are required. In this thesis, two SETs in parallel configuration are simulated with SIMON 2.0 software in order to obtain parameters which are needed to control the interdot electron movement. From the results of the simulation, it is obtained that two SETs in parallel configuration will act as two independent SETs when the interdot junction capacitance is above 5×10–18 F. The interdot electron movement occurs when a potential difference exist between the two QDs. The same potential difference must surpass the required minimum value which is influenced by the interdot resistance and capacitance. The bigger the resistance, the required minimum value of potential difference will be increased while the bigger the capacitance, the required minimum value of potential difference will be decreased.

ABSTRAK
Penelitian dalam bidang nanoteknologi telah berkembang pesat dalam dekade terakhir ini, salah satunya adalah Single-Electron Devices. Dalam skripsi ini, kurva karakteristik arus-tegangan dari divais single-electron transistor (SET) disimulasikan dalam kasus empat parameter kerjanya divariasikan secara satu per satu. Keempat parameter itu adalah kapasitansi, resistansi, temperatur, dan impuritas. Struktur divais SET yang disimulasikan terbagi menjadi dua, satu yang menggunakan dua kapasitor dan lainnya yang menggunakan tiga kapasitor. Ketika simulasi dimulai, hanya satu parameter yang nilainya divariasikan sementara ketiga parameter lainnya tetap dijaga pada nilai awal yang telah ditentukan sebelum simulasi berjalan. Simulasi dijalankan dengan menggunakan Matlab 2008. Metode persamaan diturunkan berdasarkan master equation. Salah satu hasil yang didapat dari riset ini adalah resistansi sebagai parameter yang memberikan pengaruh paling signifikan pada rentang arus yang diukur, yaitu 10-11 A hingga 10-10 A pada struktur dua kapasitor dan 10-9 A hingga 10-8 A pada struktur tiga kapasitor. Adapun beberapa efek yang terjadi pada kurva karakteristik arus-tegangan adalah perubahan kualitas grafik, melemah/menguatnya karakteristik eksponensial dan/atau ideal, dan perubahan nilai step-width dan/atau step-height.

ABSTRACT
The research in the field of nanotechnology has advanced rapidly within the last decade, one of them being Single-Electron Devices. In this script, the current-voltage characteristic curve of single-electron transistor (SET) device are simulated in the case of the four working parameters were varied one by one. Those four parameters were capacitances, resistances, temperature, and impurity. The device?s structure of SET being simulated was divided into two, one which was using two capacitors and the other which was using three capacitors. When the simulation was run, there is only one parameter which value was varied while the other three parameters were kept at starting value which had been decided before the simulation was run. The simulation was run by using Matlab 2008. The equation method was derived from master equation. One of the results gained from this research is resistance as the parameter which has the most significant influence over the range of the current being measured, which is 10-11 A to 10-10 A in two capasitors structure and 10-9 A to 10-8 A in three capasitors structure. Some of the effects that happened to the current-voltage characteristic curve are the change of graphical quality, the exponential and/or ideal characteristic becomes strongger/weaker, and the value change of step-width and/or step-height.
