In the last lecture we introduced the concept of electric potential. The electric field being a conservative field, its curl is zero. This enables us to..
When two materials with an accumulated static electrical charge are brought close together, the two charged surfaces will seek to equalise their potential. If the difference in potential is large enough there will be sufficient energy for the charge to jump the gap between the two materials and ...
Electric charge refers to a fundamental property of matter that can be positive or negative, with particles of the same charge repelling each other and particles of opposite charges attracting each other. AI generated definition based on: RFID+ Study Guide and Practice Exams, 2007 ...
where the first term corresponds to the electrostatic energy of the circuit, Ng = CgVg/(2e) being the reduced gate charge, and where the second term accounts for the energy cost of a phase difference θ across the Josephson junction and is responsible for the tunneling of Cooper pairs. In...
(M and D represents the position on the surface of metal FE and dielectric friction layer, respectively) and the energy potential barrier difference between two materials becomes lower (Fig.1e2), which is called Wang transition model, and has been confirmed by the atomic force Kevin probe ...
Two-dimensional (2D) molybdenum disulphide (MoS2) atomic layers have a strong potential to be used as 2D electronic sensor components. However, intrinsic synthesis challenges have made this task difficult. In addition, the detection mechanisms for gas mo
Pictured are two-point charges. Here, Q_1 = 3 mC and Q_2 = -3 mC and R = 10 m, and D = 8 m. At Point A, find the potential energy of the charge of q = -2 mC if placed at point A. A charge q is placed at...
When the phone is connected to power and not charging the energy to run the phone comes from the external power source, rather than the battery, thus letting the battery “rest”. And any smartphone is always doing something that uses energy, even when it isn’t actually being used. As ...

For qubit operation, the primary control parameter is the middle-left dot detuning, ε, which is a measure of potential energy asymmetry between the two dots induced by the confining gates. Adjusting ε allows for the electron to transfer between the (0,1) and (1,0) states. As defined in...
